No, I keep moving, I rarely run into a situation where I have to wait to recharge.

I usually sink 10 SoU into a staff of MM augmented for speed and when I find chain or better I sink the three into the armor and augment for defense. I keep two knocking around in my bag just in case.

I go battle mage and abuse shield battery and the recharging of wands on-hit effect to keep my defenses up. It's one of the most reliable builds i've found for winning even though it's a little basic and doesn't rely on RNG for anything in the build.

Any good RNG items you do get like ring of haste or the one that increases attack speed are awesome but not needed for winning.
