I am wondering why so many people are socketing for the 5/7 agi/stam gem. beyond getting the set bonus/number of colours for the metagem, isn't it better to go for a 10 agi and a 15 stam gem instead as it would give another stamina?
I've attached your graph to this post for when imageshack vomits forward the frog.
I have a question on your point about not having any tier 6 gear. Does this mean if you do not have tier 6 that a 5 cp cycle is always better?
The math says yes.
Under normal circumstances, both cycles are not too far apart from each other. In such a situation it's best to switch between both cycles. So if you have critluck and after 4-5 seconds worth of rip you're already sitting on 4cp, go on. If you however have bad luck and still have only 4cp after ~9-10 seconds, do a 4cp cycle.
The math can only cope with average numbers, but it would be dumb to stick with only one cycle and ignoring your critluck.
