Iam a bit surprise that you ask people if they eventually agree for multiboxing , but its a good thing because at least we can see that wherever we are from,we all have the same point of view
if i try to do the pro and cons of multiboxing, well for th ecommunity there is too much cons,multiboxing = ruining the economy (because the ;ultioxer will rush and take all materials) ruining also the auction house ( if such features will be include) and have absolutly no regret to have this negative impact ,according they get richer ingame.
It can also ruining the pvp,classement etc
My last resume is , if you ,dear dev,want to do a game 'from the community,for the community' , and create a clean competitiv environement, then the multiboxing should in the top 3 pf the worst thing you wanna authorise ingame
