Fair points. I have updated his powers to be master and thinker in a one block radius. The power he has over people is not overwhelming though it does have a potential to seriously trip people up in combat and or manipulate people outside of combat. Mantis has no ability to control, only influence. The perfect soldier aspect is to offset his rather limited powers. If ever he would come against any type of superhuman head on he would be crushed. He is more of a diplomatic, manipulating soldier.
