That’s… what multiboxing is.
1 guy, opening several clients to control multiple characters at once.
And um. Be real with me here, I highly doubt that anybody is going to control 6 characters at once, having to manually input /follow commands, and tab through each window and tell each character to do things like mine, herb, or skin mobs and/or use abilities.
I can see someone multiboxing a priest, for example for infinite heals to do solo questing or something, because all they’d have to do is just quickly tab to cast heals and stuff, but running a 6+ character setup? You’d need automation to make it worthwhile.
I would be very… very… very careful with saying “Hardware is okay!” because I’ve seen blues in other threads where people ask about using hardware to stuff like that going “You shouldn’t risk it”.
EDIT: Yeah, using hardware to get around a rule about software is usually bad, and Blues usually warn about that. They don’t like you using hardware to circumvent in-game limitations. I doubt they’d like you using hardware to circumvent a rule about software input broadcasting. The point is, they don’t want you broadcasting input and I’m pretty sure that if you could come up with hardware to do it, that would similarly be against the ToS.
