AeRO sounds like a server for you. The server is currently just in it's beta (where there will be no wipes aswell) so players opinions are greatly appreciated at the moment, and GMs listen to all suggestions given.
base cap of 120-180Server cap is 150/70, while a little higher than usual, it still offers some degree of customization.No custom Donates, period.Unsure of this, the donations would probably be customised when it comes to the point in the end, however at this point nobody knows how this will turn out to be.
server population of 50+Currently a very small population (9 being the peek) however with more people and more people voting, the server could become larger by the day.rates between 20-200 are acceptableThe rates are 700x/700x but as you said earlier, you care more about a casual PvM game, so the rates offer that although not everything is completely soloable.custom items are acceptable, provided they are available in game.Custom items that are made are being put into quests that anyone can do, however there are some "beta only" headgears going to be floating around, that the effects will change after beta has ended.i could care less about WOESmall population... Beta...PvM wise, character powerlevel wise, there hasn't really been any modifications as of yet, the greatest being special weapon quests for each class is being made that is better than any other weapon but is only 1 slotted. Again, because it's in beta, you can post suggestions on the forums and the GM team and players will comment on them.
Despite not being completely what you want, I hope you consider atleast looking at it, however I understand if the population is a problem for you. Thanks for reading.
