This tier I felt far from needed. I watched in bitter awe as just about every other class out bursted me by a significant margin. The most frustrating was affliction locks, a supposed DoT class, peaking well over 200k dps with burst. "Rogues have a lot of auto attack damage" was said. Well, okay, I'll make up for it later, even though it seems like a stealthy assassin class should have more burst than most classes.
And yet, I wouldn't make up for it. I felt like a liability. This fight is range friendly. This fight, too. Oh, you're working on heroic elite protectors? Sorry, but the third phase it's imperative to stack with the range group to healing you is remotely feasible.
In Cataclysm, at least, my Rogue still brought excellent dps that was competitive with the best classes. Rogues had a few unique roles on fights, such as evasion tanking on Deathwing tentacles, or sub spec bursting on spine, which was exciting. While it was frustrating to receive a welfare legendary AFTER content was complete, at least you eventually gave melee an added buff to make up for the difference for the liability that melee was.
In MoP, the last enjoyable part of raiding as a Rogue was respeccing to the encounter. "Garalon is up next." Great, I get to respec combat to optimize myself for this fight! You said you didn't want to make combat "mandatory" for double target cleave fights. That mandatory-ness was actually OK with me - it made it fun to do something different. Now, it's apparent that the final niche of Rogues is being eliminated with the blade flurry nerf.
I ask you, why should I play a Rogue? Rogues are the only melee class with only one role. You need to give us much more utility to make up for this narrow position. Yes, I know you are giving us a small raid cooldown with smoke bomb, but it needs to be broader.
Why should I play a rogue, if I can get the same gear on a monk or druid, but be able to bring two different roles to the raid with this one set of gear? The same goes for countless hybrid specs, some of which use the same gear (which is huge in a 10-man heroic guild where RNG can really hurt dual specs with differing gear).
Why should I play my rogue, if every range class out bursts me during burn phases? Why should I play my rogue if every other melee class has alternate roles available? Why should I play my rogue if I have weak raid cooldowns? Why should I play my rogue if every rogue spec is the same?
While I do believe straight dps classes should be slightly above hybrids, I am not asking for just a buff. I want more utility. I want niches where certain rogue specs excel. I want to have fun again.
