and another ***** who relates this with retail. i feel sorry for your IQ, if it even exists. anyway, WHY was multiboxing allowed on retail? well, if you knew the answer, you wouldn't be connecting retail with this, as in order to play on blizzard servers you need to pay a subscription money for each month you play. here, you don't have pay a single thing in order to create an account, download the client and play on any realm and for how long you want. lordaeron already has a ridiculous population and even over the cap during weekends.
let's make an extreme example: let's say one person decides to make 7000 accounts and characters and play on retail. he would have to pay 91000 USD a month. let's now say the same person wants to play here, he doesn't have to pay anything and he alone can take the whole server for itself, forcing other 7000 players to wait in queue until he decides to log out, whereas without that botting program, he wouldn't be able to keep all his characters active before the server disconnects him for inactivity.
i'm well aware that no one can have 7k accounts and even if one could, the server wouldn't hold it, this example was just to illustrate the point that every single player slot in this matter is important. even more so as there are no premium account queue skips and people would rather play than stay in the queue.
for that reason, and the pvp one, multiboxing SHOULD NOT be in this game, disregarding how it is on blizzard servers.
