Nope. It's simple. You can easily break something that is not broken.
Examples include...
Rogue Sneak Attack suddenly requiring a save based upon your dex modifier (it's a rogue pre-req right!) would gut lots of rogue builds. Does that then mean that rogue sneak attack was OP?
It is decided that rangers no longer get feats from their class unless they meet the pre-reqs. This would effectively destroy some builds. Does that mean not having to have a dex of X and a pre-req feat for bow stuff is OP?
All spellcasters suddenly have their SP pools cut in half. I think you know the outrage this would cause. Does this mean that all casters had too much SP before and were OP because of it?
It is decided that the most used spells in the game must be overpowered because people use them more then other spells. The following spells are removed from the game heal, mass heal, wall of fire, reconstruct, blade barrier, haste, resists, blur, displacement, mass cure spells, and greater heriosm. Clerics would consider that pretty devastating. So would arcanes. Does that mean that all these spells were then over powered?
