I'd definitely agree that Pummel needs some kind of buff. It's currently relatively useless since, as you stated, the whole point of the skill is for enemies with high Dodge - but then when you try to Pummel them, they just dodge it! An accuracy buff definitely seems like the way to go for it. Heck, I wouldn't even mind having the move do no damage, if it hit automatically! You're using the move for the utility of the debuff anyway, not the damage.
I'm not so sure about Eviscerate, though. Prior to the nerfing, Eviscerate had absolutely insane damage potential against organic targets (especially if you "stacked" your bleeding procs with bladed armor and/or boots and a serrated knife or bladed combat gloves), and it's still pretty wicked. With my recent high-dex fist weapons build, I had up to eighteen bleeding procs per turn (for an average of six or seven bleeding wounds per turn). That meant I could end most turns with an Eviscerate "nuke" that would do 400-450% damage (100% base weapon damage + 50% per bleeding wound) if I needed to finish off my enemy before ending my turn. Since the enemy would generally be dead after that attack anyway, it didn't matter if they were still bleeding or not afterwards.
