I would SERIOUSLY LOVE to see Anti-paladin (CE knight/paladin) as a new player class in DDO. I used to play the he!! out of the shadowknight class in EQ. APs are in the D&D world and would be very easy to make as either a totally new class or perhaps a build for paladin. The build for an AP would be best as the EQ build, part warrior/part necro. Adding feign death (or whatever you want to call it) as a skill for rogue, artificer, necromancer and anti-paladin would be awesome.
On a separate note, please, NO MORE TRADESKILLS! I switched from EQ to DDO because it was more straight forward. EQ became so complex due to tradeskills, epic mounts, in game games and in game currencies and other bullcrap. Leave DDO less complicated and more pure gaming.
