2/3 of the engineer elites are just a big disapointment in sPVP. One is a potion that gives you one of two other classes elites (and not even very good ones at that) and mortar is short ranged, low damage, and buggy. If I try to spam the 1 shot on an area my shots start to glitch out. The only thing it does that is any good is the 5 knockback. Its only decent at killing necro mm if they arn’t looking at you. But necro MM is generally bad itself.
What we are left with is supply drop, which is good, but I dislike it, it dosn’t fit my roamer playstyle at all and I’m not usually specced for turrets.
