yeah it says you must also spend points on arming terminator armor, why doesnt it say that about artificer armor or regular power armor for that matter. All 3 versions must be armed, unless you want to go around punching the heretek, the alien. . .
once my group gets up to that level i will allow them to sig. terminator armor. However, using it all the time will cost them. Terminator armor simply will not work in certain situations and would make completing the objective impossible. Unless it were vital for the mission I would not put my assault marine in terminator armor, to slow, to big, to noisy. Jump packs only make noise when you're using them.
