im currently downloading this game and i wanted to know
Which server do you recommend me?

I recommend server: "Uninstall". This game is called "BotAge" with duped economy (if you have no idea how to dupe items, you mean nothing in this game, unless you spend irl money).
Trion doesnt give a single fuck about patching bugs, hotfixing exploits and (what should've been done after release) repairing major bugs like duping followed by huge roll back.

I didn't find the server uninstall =(

if your playing on north america

you should try :

Ollo
Kyrios
Aranzeb
