Apperently, CoPals for some reason is really popular. Don't understand why as it's the same as official...but I thought I'd give it a try.
My Evaluation of CoPals:
The Good:
Server has a nice amount of people to play with. Haven't encountered a chinese NPC yet.
The Bad:
Lag is horrible. I am never below 1100 ping. Bullies seem to torment new players. It was hard leveling in the spawns because higher leveled people would come in and kill steal majority of my monsters. Lottery is used too often. The chat box is filled with people winning stuff. People think it's funny to stand on top of NPCs. In trade, silver is useless. Anywhere I looked, CPs was the currency. I don't know how easy it is to get CPs....but come on.
In the end, if you like the way official servers are handled, but don't want to play official, join CoPals.
