It’s actually 20% frequency. You’re right, though, that having 200% AD should not generate any more lag than having 1% AD.
That said, Blizz does not seem to be in the business of doing very much with AD. There’s the +AD stat on items, and that’s it. I don’t know why they do things that way, but it does seem to be the case. No item modifies the way AD works in any way, and AD is not included in any set bonus.
Sure. Free and I were pretty clear in our proposal that any and all of our proposed “List 2” changes would need to be tested in a PTR.
Rend can’t crit, but it CAN proc AD.
