EDIT: Nevermind, don't catch me up on it, I've pondered it and figured out what the complaints are.
To the shared loot complaining: This has nothing to do with the suit. The suit is a tool that players bring to use, just like pills and rings and hats and any other armor with boosts. Your complaint is just that it can't be purchased anymore. But that isn't the fault of those who have the suits. Nor is their use of the suits an "exploit". They bought it, they wore it.
Instead of blaming those who bought suits, you should be looking at the distribution problem with shared loot mobs. If a player uses all of the tools they have purchased in order to apply more damage, they have invested to do that. Distribution should accommodate that and it should never change. But the extremely lopsided way loot is split up causes a lot of lower damage participants to see a much smaller share of of the distribution than is fair.
How about suggesting a fix to that, instead of punishing your fellow players for spending their money and investing in gear? Unless we want everyone to wear the same thing?
