EMPTS takes 1 ensign slot eng team 1 an ensign slot and Aux to SIF 1 an ensign slot. 2 lt slots remian. Eng team 2 takes one of those and RSP fits in the final slot.
While its true the ship is limited to low end heals it also has a higher damage negation in the first place as I outlined before. Its also true people have killed them but that seems to have more to do with the pilot skill than the ship. An OP ship in the hands of a sucky pilot fails to negate the nature of the ship
putting 2 TAC teams and 2 ENG Teams on the same ship won't work out very well ;P
