WW cant tank smite and like GIFF said, a good smiter with telesmiting skills will destroy any wwsin out there.
besides the fact that you can abs the psn dmg with a simple antidot or andy's mask.
have you ever dueled a good telesmiter that used HF flashing and clegs (or in europe nl with 10% slow from BB as well) at once? your traps will be set like ~1/sec and your ww speed will slow down so much that it lags like hell (whirl at one place) and you will stay in the smiter's range for like 4 secs if he teles on top of you, so basically its a hopeless duel if the smiter knows what to do and is willing to lame a little bit.
concerning kicks: i disagree with all those who say ww>kicks always because i bet there is no one or maximum 2 ppl who can always and on demand make perfect triwhirls with a range 2 weapon. overshoot once = tanked by any nec/sorc. pretty riscy if you ask me. it works fine against crap casters, but if you are not a master @ whirling, a good caster will find your mistakes and kill you instantly.
with kicks, you cannot overshoot. and have you ever heard of DT-Chainlocks?
check this just to see what i mean, the nec is obviously a newbie though:
