I play a crowd control/healing focused bard that's currently level 5. On fights against things that can be held that consist of groups of melee that are non-dangerous and casters that can pack a whallop is to run toward the caster while casting hold person at every possible cooldown until it sticks, then melee'ing it until it dies or I have to hold again. Outside of that I rarely do meaningful melee in full groups as the fighter types usually have everything else dead before I get a swing or two.
For the times that I'm facing only helpless mobs would it make sense to buy a +1 or +2 pick? It seems like the x4 crit multiplier would trump everything else in situations where the mob is helpless.
