Shade of Aran (PVE EVENT)
I think this boss requires some adjusting as well.
+-25k aoe fireball damage every 5 seconds to everyone (40 people) in 40 yards is pretty hardcore in my opinion, especially combined with a high HP pool. In other words this means if anyone is not topped between 2 fireballs, they will guarantee die. And you cant really afford to have many people healing, because other bosses require even more DPS (this gives me another idea, that it could be nice to know at the start of round which boss will spawn).
Fair adjustments could be:
1) Reduce fireball aoe range to 30 yards, so at least casters can try to "play around it", rather than tanking it.
2) Reduce fireball damage by a decent amount, so that you would survive at low HP after 2 fireball hits.
