ExperienceRO is downright amazing! Don't have to grind for zenny, don't have to focus on grinding just to get the good enough gear to pvp or mvp! It's readily handed out when you join and is a HUGE selling point for me. It's difficult to farm especially if you have things you have to do in real life and ERO allows me to have a good balance iwth that. I love this server so far! :)
