Bloodrage and Berserker Rage have been off the GCD for ages. Rage has mattered at various points of WoW’s history, and neither ability has strictly been used on cooldown in the past. It’s a new mechanic causing the problems.
I disagree. I think it is just because rage actually matters as a resource, so things that provide rage now feel like very important buttons instead of convenience abilities. We could remove Raging Blow and Fury’s mastery, and warriors would still smack Bloodrage on cooldown just because of rage normalization.

Currently, Deadly Calm is the only way to proc Inner Rage aside from auto-attacking for ~15 seconds. I’m not sure where the disconnect is. Lack of confidence in players’ observations? We’re certainly not trying to circumvent the limits and discipline of a rage system.
Players in beta are either in Icecrown-level epics or quest greens. Nobody has gemmed and enchanted Cataclysm raid gear, or even heroic blues yet. Rage won’t scale with gear to the degree that it did in the old model, but it will most definitely scale. Haste, hit and crit all have a huge impact on rage generation, and you just aren’t going to get high ratings for those until you’re in endgame gear.

On a dummy in live (my benchmark for the leanest possible rage income), I’ll only get into trouble if I start fooling around with Heroic Strike or Cleave. That is, I think, roughly how it should be.
Sure, but once you have Blackwing Descent raid gear, you’re still going to have a lot more rage. If you never run into rage problems now unless you hit Heroic Strike, then you’re going to hit pretty quickly the situation where you never run into rage problems even when you hit Heroic Strike. We normalized rage, but we didn’t want to normalize it completely. Gear still makes a big difference for rage income — just not damage per se.

If you can, at least consider the relative angle. I haven’t tested Fury for a couple of builds; just whacked a dummy for ten minutes on a pre-made after doing the same with Arms, and it was like night and day. Granted, in its cozy epic-80 niche, Fury still has rage close to where it should be. I wasn’t staring at greyed-out buttons unless I did something stupid. Really, really fun and free. Just couldn’t get that with Arms.
Yeah, I’m actually more worried about things feeling good for Arms, because Arms just doesn’t hit as frequently as Fury, so the income is going to feel spikier. (Source)
