I am completly agree with you and my comment goes in the same way. I regret that vanilla builds only focus on damage and neglect all the other aspect because its the only way to have viable characters. I looked for intensive and intelligent encounters where CC is difficult and necessary.
IMO your decission goes in the right direction for that. I was just afraid that the stat bonus distribution that you propose create a new meta where stacking 10 AP always prevail no matter the build. I know this is hard to know before testing with the final product.
Either way, I am glad that you still working on this project and my helping offer still stand ;)
