yes, you no nuke, so you bored
Just suffer the next 2 levels on your S/S, then when you have a nuke you'll be badass, and if you get the other one, you'll go "WOOOT!!!! F^@$ yeah, take that you stupid mob"
On the cleric/warlock, this is a good build, i've seen people pvp with them, talk about staying alive as a INT euro, you'll get buff from cleric, and hp passive at lv40, then you got this other skill on warlock which you get to suck your opponents hp, then debuff them and kill them.
I'd say its a fun build, since you can curse multiple mobs and they die one by one
