I have a fix!
Reduce Rage duration to a minute and put it on a 7 minute timer that ignores enhancements.
Greatly increase the damage buff, like astronomically high, insane numbers.
You would lose access to taunt, gauntlet would stop working... and it should probably add a fear effect to your attacks and taunt auras.
The crash includes a massive PBAoE knockback that drains all your endurance, stuns you, THEN placates you.
Then I would make all the punches in the set not look so stupid and remove the knockback from Hand Clap. It's just a stun.
I would then put anyone with a spreadsheet or "pylon times" on ignore and go join a bunch of PUGs and see if it's fun.
Then I would take one or two off ignore if they promise not to whine and just tell me the numbers. I would balance the whole thing so that a build without rage at all is slightly above average.
Boom. The power is thematic, the set is balanced, it doesn't look so goofy and it makes Controllers, Defenders and teamwork relevant again.
Oh yeah, and make Hurl a very narrow cone.
