Syn issue still work even in rank CC if time correctly since crystal conflict came to be. People still abuse system at a time of day. Same abuse happen with gc war when Onsal was new and well everyone join flames to get the mount with long ques. I'm pretty sure there is still win trade in CC its not has bad when it came out. I rather they remove battle high all together be less of a pain with damage output, and probably do something the amount of infinity crowed control you can do to someone in frontline.
