well, i can say im actually pretty impressed with how titans grip is working out. the change to a -5% penalty from a -15% penalty made all the difference. leveling as TG fury is now not only viable, but actually quite enjoyable. i almost feel like my blood DK, where i can grind nearly endlessly, killing solo mobs in a chain, or groups of 2-3 with little-to-no downtime.
the key is getting that 7% to +hit before talents. i think once youve got that TG fury gets much nicer. until you can get that 7% its probably going to be a bit rough, but ive seen enough +hit gear in the xpac thus far that any undergeared fresh 70 (or even more casual long timers) can probably give TG fury a decent shake once they hit 71 or 72.
so if youe got ~7% +hit available, and havent tried TG fury yet, give it a whirl. its really a lot of fun, and not too bad in pvp either (in terms of the random world **** that happens while you level). double crit whirlwinds with imp WW and unending rage are just smexy.
