You're assuming a lot about my tone that wasn't there.
Apologies if my message sounded harsh, it was not my intention. I should have added a

at the end.
Also, the warrior AE is attached to Thunderclap, which is on a 6 second timer, so you can run around dropping those little AE spots everytime thunderclap comes up. Unless they've changed something very recently.
Honestly I don't believe much in what is ingame at this time. Until testing starts with raid instance bosses and lvl 85 characters, the tuning of tank abilities will not take place, and rigtly so. I'd be very surprised to see them use the dungeons as a tanking benchmark. I remember TClap applying the attack speed debuff, and I'll check again as soon as I manage to login without crashing to desktop 10 seconds later..... BTW what I indicated above is the current objective they have for tanking mechanics (which may very well change next week, of course).
I also don't believe a thing about the current cat status, energy costs and aura durations in particular, this is why I find any analysis which popped up on various blogs/forums to be premature and, in the end, useless.
