Bundled enemies, attacks, PS4 can't keep up and stalls game

When mapping, I can't go fast enough to make this enjoyable. Nearly every mob pack slows my system down, it stalls, i can't move and i die (most of the time) when it comes back. One instance today completely froze at T1 boss, had to restart game. Luckily i didn't die, but the abundance of mobs, attacks, movement, slow this game to a creeping halt. I would recommend reducing pack sizes, animations, etc. in order to make this game playable. It's too difficult on the PS4.

Side note, having to use flasks in awkward hand positions literlly makes me use L1 & R1 only. This is for all console gamers, make it easier to hold a controller in order to play this game
