thought i'd add some info for the second name
here's the situation:
imo best way to fight this mob is to have the whole raid standing behind one of the greater barriers (see the green spot? yup, thats the raid/a player/whateverrr).. mob doesn't seem to have any heavy AEs..
having the raid standing between a greater barrier and one of the fences, you'll see some bubbles/ light blue flames coming up from at least 1-3 of the fences.. one fence is
allways free to get there.. and that's what you're supposed to do:
in the graphic above there are 3 fences with bubbles and only one left without (you'll end up in that situation at 30% of the mob (?) ).. hurry up to the fence without bubbles, wait until bubbles are gone and get back to one of the greater barriers..
randomly there's a kick - some players get the message "Time to fly, <insert player's name>!", but some won't.. seems to be a bug, but nvm - just get yourself back behind the greater barrier as soon as the bubbles are gone and you won't be kicked down..
I experienced that you don't get a kick while bubbles are up, but not sure about that..
