DRK went through some big changes to bring it into line with other tanks, so there is a salt about it. Additionally, I'm finding that other players in dungeons are jumping on the bandwagon for that - you'll catch more hate if ANYTHING goes wrong, and will sometimes be told you're playing a trash class. Ignore it all. DRK is plenty of fun to play and can do its job just fine. You won't have the burden of changing your playstyle, because you never played the old version. I can't honestly say that Paladin is more or less fun, because I haven't bothered to level it farther than Provoke level - class bored me to tears. Pick whichever one feels right, and try not to listen to people saying one is better than the other.
