My complaint is that warlock boosts rogues too easily.
Just take 2 levels and you don't have to invest skill points in climb, and you get a big, fat +6 to jump, balance, and tumble. It's like an unconditional prestige class for 2nd level characters.
Even a 1-for-1 rogue/warlock won't lose out on the classes' special attacks, because a sneak attack with eldritch blast will add up to the same damage as either attack would for single-class character.
