Go farm gc or anakim if you need exp. You can have fun playing nonstop, not standing semi afk and waiting for rb. Who cares about rb, system is broken after lastest patch, rbs die as fast as normal mobs - huge absurd. But you have boosted farm zones, as random you dont need RBs at all after 65 lvl...
Yesterday farm in Anakim (3h) in 6 ppl party - not some plvl duo, 35% exp scrol owl fish stew tower scrol. Party without epics can make atleast half of it
Anyway server doesnt have problem with update/features/farm zones/RBs. Current update is very balanced, Op classes are nerfed compared to official version(DA/summoner), weak classes are boosted(elemental mages, some tanks, archers, pp), each type of party has its own farm zone, can chose farmign adena or exp, update is not the problem. You can make update of dreams of every player, you can make every player happy(which is impossible) but it will not bring new ppl here. Make some action about bringing new players or updates will not have any effect.
Check how other servers do it. Organize kind of fresh start for new players(you decide how you do it not to fk old server)
Consider Paying streamers/clan leaders to join here like other servers do for 1st weeks of "fresh start"
