Id recommend ASGARD really fun 5 bots solo progression custom world bosses, custom augs (found via hints NPC will shout out in POK sometimes) everything is all/all want to be a tanking wizard? Go for it! Custom npc in hub (pok) buff bot/teleporter and mercs are enabled. Xp is not slow or to fast pretty well paced leveling. Max lvl is 75 I think quite a unique server check out a more detailed description here
