+1. I think battlefields in general could be reworked to fit more level differences.
Just add a balancing buff to level 18 players that is enough serious to match level 19 players with same buffs.
Same could be done with level 16 and 17.
Just an idea. New levels adds more separation and this has to be fixed with the actual population... We are not RU server.
Balancing buffs, if made properly, would make things equal and make more players partecipate, by reusing the same population this server has.
For example if you checked dungeons you already saw that there were over 100 players in que at the same time and the battlefield was always starting.
