I found a small way to make things easier in the Raid, not one that seems too impactful, but it’s quite easy to reproduce.
I took a printscreen of the encounter, but I’ll elaborate a little bit as well
I had a bit of issues taking a clear screenshot in combat, so here is one first to show the spot you can just hop onto http://i.imgur.com/RrJmdh6.jpg
Then, if the first trash mob is the green one, you can lure him right in front of you.
The teleport skill and small blue balls will still deal damage, but you will not get teleported anywhere else.
So you can just auto attack and kill the trash mob with a little sustain
