It works very well with 3 of these, a tank and a cleric.

Sab does have a bunch of bombs, but IRC only one or two are click targeted. It has other cool stuff on the charges -- like not gaining aggro while you attach the charges (you do no damage with them until you hit the finisher and then you get all the charge dam + the finisher dam).
