About the new Darius and the item changes

I just tried Darius on the PBE, and he's new Q animation is so weird to me. I think Riot just not finish up the animation or something, it feels like a drop frame animation. Not to say, he deal a tons of damage without damage item. I build the new item on him (Titanic Hydra) then full tank and could do 900-ish with ult, TRUE damage, and and could kill champion really easy. Otherwise, he is fun to play, and the new effect on that ult with the minions is just so amazing! You just look like the master of the battle that everyone is fear off, but on a personnal touch, I won't make the allied minion fear, cuz, you know, you're their chief.

Final, I didn't really tried the item change, but I tried Warmog, and holy. When I was 18 with and full build on Darius, i was having 853 or something health regen per 5sec. That's insane! Maybe a little nerf on that would be good to balance the item that, imo, was ok.

Sorry for bad english, it's not my first language.
