does anyone else hate the uber klaus on the eckoning or is it just a skill issue?

uber klaus just like every other bo6 mini-boss (barring the abomination) is just a complete bullet sponge designed to distract you from the fun youre currently having.
it is easily the most obnoxiously designed mini-boss in treyarch history, it does either 0 damage or melts half your health bar in a second or two, which leaves you to either 1. getting finished off by the zombies in a death that doesnt feel fair at all or 2. carry stims around due your health not naturally regening fast enough.
it just seems like half of the special enemies in bo6 are either obnoxiously designed or just spammed to hell. bo6 cant tell the difference between a panzer on bo2 where you go "oh lord not him right now, im so fucked" and the uber klaus/ amalgam which is "god damnit not you again, i guess im just not gonna have fun for the next 2 minutes as i run in a circle dumping my mag into it".
it really sucks bc theres some stuff in the reckoning that makes it fun to play but the uber klaus is so poorly designed that i just cant bring myself to play that map anymore.
little things like this really do add up and make you realize that alot of bo6 is just straight up a poorly designed game. oh well, atleast it seems like bo7 is just bo6 just with less of the stuff that makes the game suck.
