Wanting a fresh team they will either do something never seen before in eSports, or totally fail in refreshing their whole team.
Until August 10, STX SouL will put all their playesr, A-Team to B-Team and practice partners up for trade for new players in order to bring fresh blood and a huge change into their team, but also in the progaming scene in general if this succeeds with several teams.
In case this will succeed STX SouL might be a totally new and different team and so will other teams change and maybe even your favourite player might find a new team.
Personally I think that many players rather want to stick to the people they already know and not really want to change their team, also those who always wanted to be in STX SouL's team might not want to go now, as the whole roster might change it then also the reason for their original wish.
