We've got some surrender updates hitting PBE going in for 13.16. Intention here is to make surrendering more of a team action rather than 1 person spamming FF every 3 minutes, along with other misc improvements. We plan on doing more of this type of systems work going forward.
Changes include:
6 minute cooldown for a person to start a surrender vote (3 minute team wide cooldown remains and takes priority over indiviual cooldowns)
Anonymity for the person starting a surrender vote
Surrender votes automatically resolve if they can’t pass
Surrender box now indicates what type of surrender it is
