Kittah, -you- bitch. Sure. But you won't be up in arms on the forums for FB only hitting for a small amount. You know on average the numbers are okay(ish). The people getting hit for 4k with FB won't be storming to the forums either to brag how a Feral only hit them for a small amount. Getting hit for a 50k crit though (whether it's Mind Blast, Aimed Shot, Arcane Barrage, Ferocious Bite or what-not) will have people whining on the forums. And, to be blunt, rightly so. I'll gladly have it drop down to ~35k crits if it means the bottom end goes up by an equal amount.
Steellynx, I'm not sure how PvP-ers would react. One has to be careful already anyway to not get CC'ed away from your target for part of Berserk's duration. While it does grant you 'new' energy to use once you connect again, it can be annoying. Opening up more kill opportunities while losing some pressure would probably be a fairly decent trade-off.
