Hello everyone. New to CoH so I don't know much about what amounts of certain stats are too much or too little. I would like to solo as many things as possible. Going to make the best of this, come what may. Running this Brute on blueside so no Mu Mastery. 
  
Specific areas of concern I have: 
 
Considering the build's other survival stats such as regen, resist, etc, is the 10.5% dmg buff from Assault enough to warrant dropping Divine Avalanche or would the stacking DEF buff be better? 
  
 
I have chosen Energy Mastery as I wasn't too impressed with available Pyre set buffs. Unless of course, as I mentioned earlier, EM gives too much of something and can easily be replaced with whatever buffs Pyre sets would give. Or any other Ancillary for that matter. Changing this would probably require dropping slots from Soaring Dragon, Maneuvers, and Golden Dragonfly. 
  
 
Just how much ToHit/ACC do I need to hit things as often as possible? From my understanding chance of hitting is limited to 95% max. Should I be looking for a certain number with each attack's accuracy? If I get a debuff on ToHit/ACC, how much would typically happen to a player and would it be worth accounting for that to make sure you are always near the max chance? If I have too much currently I could possibly switch sets for more rech, dmg, etc. 
  
I'm aware certain Adaptation effects are not shown in Pine's currently.
