As most of warrior (i guess), i am very disappointed by the warrior in 4.0.
"Annex" skills disappear, since it would have been so simple to gather inner beast and fell cleave or triple cleave and decimate to save key bindings.
About tanking i am worred about the lost of "flash", which was perfect for pulling packs and save TPs. Now we will need to save IB gauge for saving at least one Triple cleave. I guess that the new mitigation skills will equilibrate that. My disapointment is more in the philosophy of tanking : i want to play a tank based on vitalily, that means a tank which can regen its life. In 4.0 War looses self-healing skills, but do not gain any others. If i wanted to play a mitigation tank, i would have played PLD !
About dps stance (i voluntary do not speak about OT rule, because to my mind war will not OT anymore) it will be so boring to be limited to only fell cleaves : is that what WAR is only good for ? SE : you might be kidding ?
