I'm gravy.
And I'm actually familiar with Binders - Shadow Magic was cool, if a bit on the rigid side and more complex to explain then to use. Truenamers were actually broken in two directions - unplayable at the mid game unless built very specifically, but busted in the other way the moment they can create infinite Gates. Binders were probably the most cohesively designed.
I would say you can bust a Binder, but you have to be pretty specific in building them. Zceryll is probably the only one that is potentially OP, but that's 11th level at the earliest as far as I can tell. Even if you take that one, though, you won't be more dangerous than a Sorcerer, unless you built around that, and then we are going back to "specifically built to break the game."
I'll be blunt - if all that is put in front of Lev are challenges that can be solved with "LEV SMASH!", then Lev'at'an is busted as hell. I didn't take Hulking Hurler because I do possess some lingering humanity in the bitter shell that is my heart, but I have taken a prestige class that is often invoked in the same sentence as the Hurler. War Hulk is basically Cancer Mage if someone tried to balance the latter.
