It could be added but it's not high in the priority list given the very low amount of players asking for it.
Why exactly do you need more than 5 accounts?
for starters i usually have 6 or 7 teams going per race alone in different cups or leagues all with different builds
also I atm only have 2 accounts but i cant seem to make a 3rd and dont know why, it says i have reached my maximum (i use a different emial or gmail still no luck)
also have one account i want to delete as at the time i made it when BB 2 came out i didnt know you guys added the coach before the name, so that account looks like coach coach jester, its petty i know buy i dont like to use it because of that.
also I like to have a theme for the coach and teams under him, at Iron phoenix league I was Coach Kaiser and all my teams played in the same stadium the Reichstag
I am also big on stats so my 2000+ games played was only vs some the teams But now all teams will be outand i want to reset my stats (but keep the old account for reference )
another thing is i want to play stunty teams only on another account as they tend to drop my win % from 73% to in the 50's
