Well If your a Titan Like Me Titan: 42766 It take like a Few Mins Until you can Heal again So I really think you should keep Heal
I do not support this at all, this is some reason why people got Elite and above for they could get /heal, if they had started to take out commands it would be a waste of money.
People donate good money for ranks and I feel that it would be unfair to take something out (/heal) that may have led them to purchasing that rank.
