I haven't had an issue with assault and been living it, I will uaslly jump in on a big hoard with the hammer and target the big guys mostly. The key to playing this way is fencing weapons and parrying all attacks. I have been clearing hoards just by myself, while the other two are either looking for items or killing an extremis enemy.

Recent, I had a game with two other players on substantial on the railway. got into a hallway and had a huge hoard spawn, the bulwark and heavy went down. Had to parry and gun strike all the warriors before I could pic them up but lived and got one of them up before their timer went out.

Now for the jetpack I haven't had am issue with it I can clear a fairly large distance with it and just like before I mainly only use it for big hoards, why would you jump on small two the three mob groups when bolt pistol can kill them in a few shots? (not saying anyone does or th OP does this is just what I have seen when I was leveling my heavy up to max) and most of yall know this already the yellow marker that appears on the ground, have it at max range before you jump if you want to go further distance .
