warlock vs binder at wills

[Urpriest]

OoC healing, no limit, no alignment restrictions, no special feats / ability combos needed
Infinite Turning
Drain / damage healing without expending resources
Fear Immunity
Superior Scouting
Party face take 10 (no instances where you meet the king and roll a 1 and claim his mother is a goblin)

Thats just a few of the fun powers that binders get over the warlock's abilities.

Infinite Turning isn't all that meaningful when it's one attempt at a time, especially at the level you get it. Fear Immunity is something Paladins get at pretty low level, and Remove Fear is a first level spell anyway. And since rolling a 1 on a skill check has no special effect and a party face isn't going to have a negative Cha modifier, it's pretty much only going to make a situation worse if your opponent is already unfriendly, and even that goes away with 1st level ranks.

The healing stuff is more of a playstyle thing, I'll grant, but the others are really just the reason the Binder is Tier 3 and the Warlock is Tier 4. It's still not exactly gamebreaking.
