Buggy Endgame Bosses and Unplayable Melee

Hey!
All of your endgame bosses are either buggy af or unkillable by a melee character. When I got bored with farming maps, I usually go for boss farming but unfortunately, whenever I tried to farm one of them I ended up tilting myself.
(Melee, Ice Strike, Monk, Controller, Xbox)

Let's see,
Arbiter, either calls down invisible meteors or out-of-pov meteors.

Xesht, if you CC him it's over for you, infinite hands.

Regular bosses each have a different buggy mech. like Zalmarath, the Colossus has a skill where he stabs the ground and laser beams it, sometimes, the dagger doesn't block the incoming damage.

Tor Gul, the Defiler; if you're using the bell, you already have a problem with every boss, in this case, the bell goes behind the boss, and if you're not using the attack in place (whenever you're against this boss you have to activate it in skill settings) option your character hits randomly "gap" closes, teleports to the boss.

Jamanra, again if you're not using the attack in place, you have no right to miss-click any melee skill cuz in the storm + minion spawning phase, you're instantly dead by "gap" closing to the near minion and going out of the bubble.

Every single obstacle prevents "gap" close mech. as well like high-low ground, any object, trees etc.

I'm honestly disappointed, 1 month delayed beta and this amount of bug is unreal, and you went on a holiday, I hope u're having fun gj.
