Trial of Chaos Impossible Bugs

I'm getting the worst luck imaginable in my selections. There are almost none I can survive. Even so, I'm trying my best, but the way I just died was total BS. An elite mob had mana drain aura in the first room. I had to dodge blood globules so I was trying to stay the hell away from it. It of course chased me down when I was standing next to a wall or edge of the room. I had plenty of room to move around the mob but I could not move. I was not stunned. It was like because it drained my mana I was not allowed to walk. Either that or it was a full on barrier I could not roll through. It really seems to be a thing that mobs cannot be rolled through this time around. When my first two attempts to roll didn't work I was just trying to walk anywhere and I couldn't. Mob may have had me perfectly cornered, but that shouldn't be possible. Players should always be able to move or use some form of escape (like dodge roll) to have a chance to escape. Feels bad to have control of your character taken from you and die a slow death you can't avoid.
