This would be op if anyone of the humans are a Healer and the healer can help with mass pulling. If its an human tank and healer man this would be great.

I personally would like the Trust system to be editted so we can use a Gambit type system that other games like Dragon Age Origins use. For example I like my healers to make sure I am always above 85% percent.

Trusts are good in this regards as they start really healing once your below 50% but Squadrons will literally let you die as they don't heal until your below 15%.
