This is a very annoying bug.. I don't see any positive future for this.

Why don't they add a low level skill that passes through nearby enemies with the keybar?
I'm sure that 70% of the deaths in Hardcore mode are due to being cornered, and of that 70%, 90% are due to there being 20 enemies next to the new reset zone.
I recommend that you create that skill because I already realized that you don't want to add a skill like Poe's 1st skill (Dash or Flame dash... do you want to limit the options? Add to that skill 2 continuous uses for a certain time.
From what I saw they added from the beginning the melee (Leap Slam) and the archer's jump that get stuck too much because of the flies or fluffs that are nearby.
Sorry.. my English is bad I used google translator.
