Back when I didn't have much dps, I would kill his two shards and then him. Pretty often though, the shards would instantly respawn and I'd kill them 2-4 times on each side. I didn't know what was going on then, but I do now.
Fast forward to today and I usually just kill him and don't touch the two shards he spawns. When he dies, his shards remain up. If I spawn him again and kill him again, he has another set of shards that stay up.
Now I feel bad knowing that some poor group will have to deal with several sets of his Shards if I do it this way, like I used to deal with. Any chance you guys could
i) Make his shards despawn upon his death, or
ii) Make him unkillable without killing his shards?
Thanks!
