Ran the coalescence chamber today to re-flag for Shav and I have to say that this is 100%, without a doubt the most tedious quest in all of DDO.
Don't get me wrong, I love the idea behind the quest, except for a few Gripes...
G1) Once the main boss has been killed, other optional mobs will prevent the quests completion. (Defeat the fiendish ambush)
Most likely this will force the player / group to re-run the entire instance looking that singular trash mob.
G2) The end rewards / exp, doesn't come close to the mount of time required to run it.
Suggestions:
S1) Remove "Defeat the fiendish ambush" or make it optional.
S2) Setup Shav flagging to be permanent (forever) once completed. Yeah, sure if a player wants needs to mats for another GS item it can be re-run but otherwise due to G2 its pointless.
Thank you for your time and consideration.
