T2+ Mundane Class: What would it take?

[Mithril Leaf]

Give the class a +1 bonus to skills that increases by +1 per level and stacks with itself (Total of +1 at 1, +3 at 2, +6 at 3, +10 at 4, etc...) as well as a floating bonus feat per level and standard +1 BAB per level, +8 skill points, all good saves.

So would anyone be able to tell me what is actually not Tier 2 about this class? It gets craft GP gain (which increases incredibly fast), Diplomancy, true seeing (or near enough) and enough feats and stats to become an excellent uber-charger. Maybe toss pounce on, but eh. You get damage enough that you can one shot anything, the ability to convert any sentient enemy to you cause, and the ability to destroy WBL. The skills and standard BAB allow it to have decent utility in any average situation as well.
