lol this is very interesting, so many people wonder how i do it and they can't.
Well first off, It isn't easy but nothing is when you first start. i've been double/triple boxing for over a year now. most people when they do it, its once and while and they actually have to "move" somewhat to see the other screen/keyboard ect. Essentually when your doing it you shouldn't be thinking "i'm playing all these jobs at once" you should think like you do when your playing one job. When you play one job your focused on that point, most people actually get board and feel its kind of draging (especially whm in a party with a good/half decent ninja). This leaves room for more "brain functioning" essentially i'm just utilizing more of my brain to play this game. each character is essentially only being controled by one person in my mind. The biggest issues that i still have is sticky situations that require extreamly fast reactions usually send me into a "overload" lol. I haven't had much time to adjust to these high stress moments since they dont happen a lot (and you can't exactly scrimage them lol), but after this mornings incident i'm feeling more strongly about even that now lol gogo chain 4 from links
i think if someone really wanted to play mulitple characters at once they could, but they would have to teach themselves and be properly set up.
i will say that i am topped out at 3 full roles in a party. i tried 4 and i couldn't engage a monster if it was standing infront of me. ok so thats a lil over exagerated lol, i can run my mule around while playing 3 roles in a party (been there done that too weak) but i can't fill a 4th role in a party. which actually sucks because i essentually wanted to be a full party when i started this (back in my noob days when i learned you had to have a party later on to get xp lol). i was like what? i have to rely on 5 other people to go do something that sucks what if no ones on? screw that ill just make my own. which lol is why i own 8 (was 7 before xbox purchase) copies of ffxi. I had 6 characters + mule account.
