Let me start by saying...FIX YOUR BROKEN GAME!  I keep getting stuck in your delves trying to get an AP buff that is barely worth it if it works.
I just got stuck trying to get out of a Cyrodiil delve..and this isn't the first time; went through 4 recall stones and a "Get Me Unstuck" (which didn't work and wouldn't allow me to try again.  I literally couldn't leave the delve.  It kept saying destination was full or I've already queued for that campaign.  What that...?  Give me back my stones and fix the game.
