once you get keyclone working you wont have to push alt tab at all. and without keyclone there is a way to switch without alt tabbing. that is to set the game in windowed mode from the video settings menu. and uncheck the maximized box. that way you can drag the windows wherever you want and you can always just move your mouse from one to the other freely. although once its all setup you wont have to change windows unless interacting with npcs or micro managing items and junk. also the other poster was right you dont need to use the same class. youre just gonna have to work out the places to put your keybinds and whatnot. also trying to do two melee at first will be a pain in the butt. id suggest a melee and a caster as well just like the other guy. anyways definitely keep reading the wiki pages and expirimenting and eventually itll all become clear. hope you get the keyclone thing ironed im sure you will hes a nice guy. just send him a PM about it he'll answer back in no time.
