i wonder what tv will be hitting for with all cds and inq up...
also doesnt this bonus kinda boost the value of divine purpose a bit? considering it might lead to less wasted procs, and all.
The proc alone increases TV's total damage by ~85%. In my current gear, I've seen TV crits as high as 200k (which is ~280k when you include mastery), so if my t14 set bonuses were magically traded for t15 set bonuses, that'd be almost 400k (over 500k, counting mastery). With t15 gear (better weapons, more strength, more mastery), even higher than that. So... yeah, pretty huge.
It doesn't look likely to much boost DP relative to HA/SW, no - DP would only let you avoid a wasted proc when you have a DP proc from your previous TV (25%), followed by a CS - something - something - CS and both CS proc the set bonus (40% * 40% = 16%). 25% * 16% would mean this happens 4% of the time, or about one in twenty-five CS pairs that don't already include a TV. However, it may diminish the value of Sanctified Wrath, since all that hammer-spamming makes it difficult to fit in CS. Hard to say for sure, yet.
