So GC said that progressive nerfs are unlikely to happen this tier. If so, what's the point of the FoS from heroic raiding, other than "I didn't go back and lol this boss on Heroic in T16 LFR gear"? The feat specifically mentions the debuffs last I checked. http://us.battle.net/wow/en/characte...achievement#81 see descriptions.
Personally, I don't see why they wouldn't have some progressive nerfs - there are still a lot of guilds stuck on normal Elegon and Garalon, and if they cannot progress they'll probably just unsub or quit playing very much. Like it or not, these guys pay more of the sub fees than "we killed Sha of Fear first week" guilds do, PERIOD. Maybe not derp 35% total nerf like in DS, maybe 5% every 2 months or something a bit lower/slower. Or, go in and manually make changes to certain fights on Normal to remove the stupid from them, like 30 extra seconds on Garalon, or less health on Elegon, etc. People getting super stuck is NOT good for the game. But neither are super sudden nerfs like the late FL nerfs.
Elegon (N): 17177 (52.13%)
Garalon (N): 9895 (30.03%)
