This suggestion has been posed before in some of the other threads, but it's not really the focus of those threads, and I felt this solution is a happy medium for all parties involved. Thus I wanted to host a poll and discussion about it in specific, instead of getting lost in other aspects and topics.
Instead of disabling the queue to Cryodiil at a set number of telvar, simply disable it when the game considers you 'in combat'.
This will allow folks to get out without major headache (or forced into an abusable chokepoint), but without just escaping combat mid-battle. And considering how long the game likes to keep you considered 'in combat', then escape will be pretty difficult, and at that point, you probably already lost that person anyway.
I feel this is a simple happy medium, otherwise setting it at a number of telvar, there will always be someone not happy. Whether they deem it too much or too little. This would just be a pinpoint fix to repair the core issue, people escaping combat, during combat, without hurting anyone else.
Hoping for more playable races
