You have a glass cannon build with sub-par equipment and are going up against 4 opponents; what did you think would happen? The idea behind a zerker build is to kill foes before they can kill you. Your gimping yourself with subpar equipment. You won’t do enough damage to make it work, and the lack of defense will just dee you dead faster. This fight is a bit of an anti-zerker fight anyways; did you notice how when one dies, the rest heal up all the way?
Honestly, drop the off-hand axe for a shield and the rifle for a greatsword. Change out Signet of Fury for For Great Justice, and the Banner of Discipline for Endure Pain. Change your traits up accordingly. Look at maybe taking a different heal; Healing Signet with heal on crit food works wonders. Add a regeneration booster if you have one laying around.
Take out the melee first. Pick one and burst him down. Use the Rush (GS 5 skill), follow with Hundred Blades, Whirlwind and switch weapons mid-whirlwind (don’t wait for it to finish) then shield bash and eviscerate on your target. Now he is dead. If you used Endure Pain, you are not.
Now take out the second melee (because he is right there), use the same attacks on him. Stay out of red circles (he follows you since he is melee, so pick where you fight.) You may go down during this fight, but you should be able to get back up with a few rocks. It’ll be that close.
The remaining two aren’t so much a problem (I mean, you survived four of them by this time, right?) Remember to close quickly or use shield block while moving, use your cripples if they try to move out of melee, and dodge/whirlwind like a maniac, because why run when you can whirl.
