Deltascape design problems

[ZerofraZ]

I think, that some battles in the Omega raid have problems with design and these problems make trouble for melee DPS and their positional attacks.
--- First battle- the problem of positional attacks, when the boss comes very close to the wall. Impossible to make a rear positional attack. Possible solution- the boss must be not too close to the wall
---Second battle, when the floor becomes black, the circle under the boss becomes invisible (I have a white color). Possible solution- to fix the circle, it must be above the black mist, not under
---Fourth battle. The boss's coat blocks the sight and the round under the boss almost impossible to see. Possible solution- to make the coat twice shorter

I think, that these problems must be fixed
