Yeah, I hop in the arena from time to time, normally right before I log in/off, or when there's just nothing going on.
Thing is, I could care less if I kill or be killed. Its just fun to see what happens when I hop down. I don't even wear a Mantle, because its more fun this way.
I understand that PvP is much more important to you than 80% of the DDO customer base. But please don't ask them to adjust equipment based on a combat system that was added into the game as an "afterthought" to appeal to the Asian market.
Maybe they could code something in that makes spell absorption items "inert/disjoined" inside the Tavern Brawl. I could stand behind that. But not actually changing the item's attributes.
