I suggest go to the snowflake wow that is Blizzard's Legion, were they destroyed Wpvp because of the cry babies over the years. Multiboxing has a huge impact on other players, and can be used in ways that exploit game mechanics, I'd suggest doing your research..... if you can't figure out why Multiboxing is banned, I feel like you have no hope of grasping common sense.
This is a MMO....Pvp Server...... ganking happens, it's not against any TOS on any game with open Wpvp, common sense bud. Don't like it? these games are not for you son. Welcome to classic WoW on a pvp server.
Multiboxing will not be allowed on the new Blizzard classic servers BTW, Blizzard has changed their policy on the issue, and is now a bannable offense. Might want to get with the times. The only reason it's allowed to some degree on Legion is because they run a Multi-server(mega servers) which does not cause stress on the servers, and blizzard made statements they will be changing their TOS on multiboxing in the near future.
