Is the roll for a combat maneuver really supposed to be KAC+8? That seems herculean by even soldier and solarion standards. For a level 1 soldier (BAB +1) with max STR at generation (18, +4 Mod) this puts the ability to hit a basic 1/3CR CASTER array (Alien Archive) that has an unmodified E/K AC (KAC 10) to 18, meaning the soldier has to roll a 13 just to pass, and that only gets more out of hand as the game goes. The basic COMBAT creatures/thugs you might encounter very early on usually have KACs at 12 or more, meaning you're looking at maybe 20+ needed at LEVEL 1, not to mention that you'll probably NEVER hit the 5 over bonus.
Keep in mind, those numbers are also for peak stats too.
It seems WAAYY too punishing for something like that, and almost forces you to feat into specifically performing CMs.
