One more message to tell you how much dodging is killing the pvp on the server.
The removal of GP in arenas didn't fix the problem at all, people are still dodging constantly to get the seasonal rewards or just to piss people off
Yesterday I saw this flagvruki applying glory arena, got entry over 10 times, he didn't enter a single time as long as it wasn't an entry with all his alts to be 100% sure to win arena and seasonal rewards.
Clearly removing rewards from arena doesn't stop people from dodging, it either makes people not do it at all, or still do it for the seasonal rewards and dodge for it till they are 100% sure only their alts have entry.
The same applies to eob, kamar and IWW, people just dodge over and over again, many times for no reason at all like "pass 5 times then we enter 6th time" or "pass because we got entry too fast so it must be a premade!!!!" on top of targeted dodges.
I know you tried and failed to implement a mechanic to remove an entry when the instance proc or something like this, so i'm not gonna suggest the same thing.
What you could do instead, is to make it so that when a pvp instance instantly close because of a dodge (ends on the first second after the countdown is over), the team that entered gets no reward (no gp/ap/box/insignia) but get a reset scroll for the said instance (or a ticket in case of arenas, or 3 in case of a glory arena). The scroll would have to have a 24h timer before expiration so that people can't abuse and stock up hundreds of them for the next GP reset.
If you could implement this idea, you could also consider putting back the GP in arenas later since you would gain them only from winning against an opponent.
It is by no means a perfect solution and won't stop people from dodging if they want to, but atleast it won't be killing the game by wasting entries for the people who just want to play.
