Why is a 6K DPS ship that costs 10 billion isk game breaking? That's 6K DPS with perfect skills and a full rack of drone control units, IIRC, on a battleship-sized sig.
i encourage you to take this question to kugutsumen; many of the most prominent fleet commanders in the game's biggest alliances will be happy to describe the problem in depth.
i think this sums the problem up nicely - and bear in mind, it's a problem CCP created, after
being warned they were making a huge design mistake, in Tyrannis:
Why is the mothership so broken?
It is possible to create a mothership fit that has more tank than a titan
Motherships can do more damage to a POS than most dreadnoughts
Motherships risk nothing to do either of the above. They are immune to electronic warfare already and sacrifice nothing in order to have insanely strong tanks. They also risk nothing to deliver damage in excess of that of a dreadnought.
A Mothership can, if it wishes, solo hot drop a Tier 1 capital outside any tower, even "death star" towers, in the game and kill that capital ship before it can warp off or move into the safety of the tower's shields.
It can do this even in Low-security space where even the mighty Titan must give up it's Doomsday device and bombers can not use their bombs and interdictors are not allowed to deploy bubbles nor can anchorable bubbles be deployed to stop them.
In lowsec the only remote threat to a mothership is that a fleet has enough heavy interdictors to hold it down while cycling their warp disruption generators (with scripts in so they can only tackle 1 mothership at a time) so that they can get repaired.
Motherships, in fact, have the ability to fit so big a tank that without an incredibly powerful fleet you can't even kill them before their 15 minute timer if they log out while you are shooting at them AND have them tackled. (It is actually possible to fit an Aeon class mothership with over 100 Million effective hitpoints)
The only real defense against a mothership was stripped by a recent change to how fighter-bombers worked. CCP decided that, due to lag issues, they would change bombers from using missile code (which allowed smartbombing ships to reduce/eliminate the incoming fire from fighter-bombers) to using turret code (which made them cause less lag but eliminated the ability to neutralize their damage).
As a result of all the above the Mothership, not the dreadnought, is now the preferred ship to hot-drop other capital class ships. It is, additionally, also the preferred ship class for attacking a POS. Even the fact that fighter bombers can't hit a pos tower itself isn't much of a limiter because the mothership can deploy 25 sentry drones which allows them to do in excess of 4,000 DPS at sentry drone ranges which means they can effectively replace dreadnoughts as the main force when attacking towers if you have a few of them on the field. Couple that with the fact that you can extract the mothership instantly at the first sign of danger while you cannot do the same for dreadnoughts.... well... you can see why so many alliances that can field numerous motherships have stopped bothering to field dreadnoughts unless they absolutely have to (usually triggered by the other side just having a vastly larger capital fleet and they need the numbers).
the other primary issue not discussed here involves the cyno range of motherships - they can cross distances much larger than other caps/supercaps, and with the upcoming jump bridge array nerf, they also outrange subcap
fleets - meaning the most powerful ships in the game are also the most mobile. mothership blobs can do everything in the game better than anything in the game. what's worse, they cause a lot of lag, which means they can kill enemy fleets while the enemy pilots are still loading grid.
(it hopefully won't surprise you to learn that most titan and other supercap losses are due to lag, not firepower; for a long time it was impossible to even attack an entrenched enemy because loading grid would take 30 minutes to an hour, during which time the defenders would simply slaughter the attacking force with swarms of mothership-launched fighter/bombers)
Transition from r64 to tech? That makes no sense. r64 sounds like a moon mineral name, surely there is no resource called "tech". I wasn't aware that moon mining has ever been any different than what it is now, I've never seen any huge overhaul to it in any discussion of any expansions I've been around for.
the r64-tech transition was a major economic event that made technetium wildly more profitable than other moon minerals, fundamentally skewing eve's economy.
there is a resource called tech, it is concentrated in what was (until very recently) NC space, and because CCP screwed up the Dominion moon goo system, it is enormously more profitable than any other mineral - it's like the mothership of reaction chains. in essence, the technetium problem occurs because all the most profitable space in EVE is concentrated in one part of the map. one particular power gained control of this area, locked it down, and began raking in so much money that it's rumored their leaders are paying their mortgages using RMT (real money trading) profits from selling ISK.
CCP was warned about the tech issue well in advance of the patch, but they were either unwilling or unable to fix it. since then, fixing the tech problem has become the biggest issue in the EVE playerbase - the recent CSM elections were full of candidates promising to do something about the damn tech.
with luck, mittens (or some CSM hero*) will be able to ram a solution through and get nullsec back to its previous, relatively even wealth distribution
the reason the EVE playerbase is so cynical about CCP is because they have a habit of making things worse instead of better: they tried to make motherships desirable and instead made them godlike, they tried to make sovereignty warfare more fun with Dominion and instead made it even more of a soul-sucking grind, they made their game more
laggy instead of less, they tried to clean up economic imbalance and instead gave an enormous advantage to one area of the map at the expense of the rest. they just don't have a great track record in terms of intended versus unintended consequences.
