For longer fights like Baldesion Arsenal, Delubrum Reginae (Savage) and maybe future relic dungeons, how do you all think about splitting them into multiple boss instances, just like Savage Raids.

I think this would be perfect for those who:-
1. have real life contraints
2. cannot commit long time to a long dungeon fight
3. cannot play at the start time of organized groups

Killing some adds + 1 boss in separate instance will take a lot less time compared to running a full dungeon. Having this will not only provide a chance for them to introduce more quests between bosses but definitely also allow and encourage more players to participate.
