The proc has a higher chance based on two things.
Higher Recharge (less oft used) powers have a higher chance, if single target this chance is often basically 100%.
AoEs have a penalty, so single target attacks are usually better for effective use of the proc. I'd suggest the Tier1 Dual Pistols attack, since that's important to your single target damage and always firing, a noticeable increase in your DPS vs something like an AV.

So I'm enjoying the new sets. However, question, where should I set the ATO in? I was thinking of six slotting Hail of Bullets, but I think the proc would be better used somewhere else. Any thoughts?
