I promoted adepts especially for my justicar to spec for offensive bubble, but i feel like i wasted my time doing this... enemies barely stay in it and i have to risk my life to put it in a spot where enemies are coming from.
Maybe i should just promote again and go for the defensive bubble and camp in a spot shooting and spamming Reave on everything.
she is offensive support. Also you can use the bubble as a secondary detonator.
