Stuck on 14.6 hard mode

I am level 58 player with lvl 20 survivors and maxed equipment. Not getting past 14.6 hard mode. Lvl 22 survivors recommended. It is taking 6 shots to bring down a single lvl 22 enemy, so pretty beat up before I even get to the shooters. Have used various combos including 2 hunters and assault, 2 shooters and hunter, 3 hunters, etc.
Any advice for enemies at this level? They seem nearly unkillable. This is the 1st game I've played, love it, but still learning a lot. Appreciate any tips.
