Guild Wars 2

I like sending iZerker into a combo field to throw bolts (this still works based on my tests)

But how can I tell how effective that really is?

How many bolts get launched? How likely are they to hit?

Confounding bolts is rather lackluster imho. Afaik its one stack of confusion per bolt.
Cleansing bolts on the other hand (ie. place your temporal curtain on your iwarden) removes some 5 conditions within those few seconds, thus almost replacing a condition removal utility slot.
