Concerning Overpower, I doubt I'll be bothering with Battle Stance in PvE because I intend to stack a lot of expertise on my dps gear. When you aren't being dodged or parried then Overpower won't become available anyway unless you spend the talent points on Taste For Blood, spend the rage to keep up Rend, and sit around in Battle Stance. I'd personally rather be sitting in Berserk Stance and using that precious rage on my Slam rotation while keeping Deep Wounds as my only bleed.
You're missing the point. Trauma doesn't just bolster your bleed effects, it should be debuffing the target against bleeds from all players. That means your cat druid and bear druid at least will be appreciating you just as much as if Blood Frenzy was never nerfed.Originally Posted by Raptorg
Assume you are using Naxxramas 25 Spider Wing Boss 3 Loot 1 2H DPS Mace with its 586-880 damage, assuming 733 median damage. Deep Wounds should tick for about 58 damage per second, adding Trauma to this increases those ticks to about 76 per second. Assuming you can keep the debuffs up constantly, this means Deep Wounds will deal about 17.5k on a 5 minute boss fight, while Deep Wounds and Trauma will deal nearly 23k. This does not take into account the increased damage (and threat for bear tanks) on druid Mangle.
Its up to you if you think the extra debuff is worth it for two talent points, but I would surmise that it is a worthwhile investment.
