Is the Primal data center dying?

Never tried soloing them as DRG, but your avatar says you have PLD at 70. All of the ARR Ex primals are soloable by a lvl 70 PLD in basic AF gear. Might take you a while and you'll have to pay attention to some mechanics, but it's completely doable.

I don't think you can solo titan without someone else being there to break you out. I've only done the normal mode solo and this is what happened - once you get gaoled, it automatically counts as you failing the fight. I assume this applies to the extreme version as well.
