if u have been friends with other players for a long time and you totally trust each other then the best thing to do when you all have electron remote is share the accounts. one person plays and sets up all four characters in his computer and he is not afk. that takes care of disconnection problems. but only do this with people u trust and know for a long time. its also advisable to use temporary passwords though when sharing so that other team mates wont be blamed if the account is hacked.

but if you are really into bursting and especially if your main character is earth or wind then you should make your own burst team. make a water element character and two fire characters. but u need electron remote coz manually controlling 4 characters could be impossible. personally i can only manually burst 2 characters.
