If your looking for a server with trading you could try zone, era or Ol west only problem is era has a bunch of wanna be thugs who trade nudes in astro bar for shells (sellable item for gralats)/ Zones staff can barely call themselves a staff team/ and OlWest just basically traded their best developer for one who laughs at you if you give him ideas (hopefully he'll be fired soon)
In my opinion I like olwest out of all servers but if your willing to not have trading classics a great server to just dont hang with the wrong people.

(Also player count on olwest is fairly low cause its new to android/ios also zone but its been out longer and well just not many like it, era has more players then classic tho I believe but its pay2win I would say classics pay2win but its not cause you really don't need any of the stuff u can buy with gralats on classic to be "Pro")
