If you could design the Arthas / Lich king raid boss encounter
How would the fight go?
if It was up to me, I would make a phase where we fight just the frostmourn and end up destorying it. and I would also make phase where you had to fight souls that the frostmourn has taken aka Bolvar and that orc dude (surfang?).
I would also make a phase where lich king has 50 mil hp, 5 min enrage and does cleaves that do 200k shared dmg to players infront of him.
and offcourse the encounter would have void zones.
also an ability called soul link, where you soul would be linkeed to 3 ppl and you would have to stay togather. kinda like yog sarons brain link but 3 ppl.
There would also be an ability called soul trade where, you trade souls with one of your raid members and have to play as there character or something.
