Decided to run the 4xDK and ditch the pally until they are all 110.

Seems to work very well, just smash anything up - even managed to solo Halls of Valor (lvl 102/3) - tricky with the mechanics but got it working.

My issue now though is the end quest "Securing the Aegis" where the Aegis simply has a grey question mark above it, I've run the dungeon 3 times and had the same.
Could this be caused by the fact I'm boxing and have 4x same class (tank) running it? I've opened a GM ticket and they've just said it can happen and have advised to re-run :/

Because it's the main quest line it's putting a bit of a pause on progress.
