I currently play a warlock as my alt (undead to be specific of race), and I was wondering. Is it worth to drop the PvP trinket and use unbound will in conjunction with with the on use spell power and proc spell power trinket? Or is it just wise to not take unbound will and use the regular pvp trink. Any thoughts would be greatly appreciated!
Not worth it at all imo. The extra damage from the proc is nice, but won't change a game as often as your normal pvp trinket will.
UW is pretty 'so/so' overall. It's primarily useful defensively vs. caster teams, or as an offensive CC breaker to help kill/peel. The 20% hp loss makes it pretty unreliable as your only out with, say, a DK/War on you. While nothing annoys me more than the perma /reloadui game of pre-match talent swaps, I'll be going UW vs. caster cleaves, and BH vs. melee cleaves, KFC, & DK or War + caster teams. The only mixed melee I might go UW for would be Rogue/x/x.
With the amount of cc going on, you actually still want to use your PvP trinket if you decide to go with unbound will. Since warlocks deal very little damage, damage trinkets really ain't worth it.
However, if you really don't want to use the PvP trinket, you can use a battlemaster trinket ( health), as an extra "defensive cooldown" helps more then a minor damage increase.
