Coyle would inevitably have the same 13 HP as he does on heroic difficulties.
People will try,
Coyle will die,
Keyboards will fly,
Children will cry.
Is this what you want!?
make it epic, let us kill coyle and everyone will run it (yes, just to kill him)
and it would be funny.
I do think the south quests should be bumped up to maintain BB capability.
I also think if anyone needs a 0 added to their hp, it is the NPC's we have to protect. Maybe reverse scaling. The less people in your party, the more hp your npc's have.
I think an Epic threnal would be awesome. You have to do the same quests in epic, going back and re-establishing a foothold to get through the gate to xoriat and taking out the gate master on the other side. Have that part be a raid.
Have a second raid for the arena in the wilderness. Make it a bit like chrono where you get taken back to when the arena was in use. It could be tied to xoriats influence in the threnal area.
Lvl wise, this would be lvl 21-23 epics imo, similar to red fens.
They could make the non-chain quests in Delera's Graveyard epic, though, but those quests are phenomenally unpopular.
1st change i wanna see is coyle dead
and all mobs dancing over it
in a freaking timed 15 mins quest
if not im not gonna rerun it again (at least til im done with iconic lives :P i used to do it once per life, going at 10 or 11 and doing all the chain for... some crappy end reward, but kinda tired of running always the same quests... actually i use to cap with amrath and cannith cause got bored of all the iq, reavers, reign of madness...sigh)
