I've never seen alignment NOT add anything positive to my games.
HA! My anecdote beats up your anecdote. What are you going to about that, huh?
Seriously, though, [MENTION=6683613]TheCosmicKid[/MENTION] is correct; you might have a beef with alignment, in which case, MORE POWER TO YA! Start a thread on it.
But as he pointed out, no one complains about all the other jerky classes. Just jerky Paladins. And they have done so even without alignment restrictions. After all, a Paladin will be just as jerky if you wipe the LG off of his character sheet.
