Grand Arena Championships – GP Divisions [MEGA]

So this may have been answered in one of the previous questions. Im in Division 5 and need 5 teams on Defence. Before championships i remember there was a chart that said that after you pass 2.75 mil gp you have to put out another squad. Division 4 starts at 2.5mil. So has this been changed to go by Division? or does it still remain the same (I.E. does a 2.5mil player now require 6 squads on Defence as opposed to before 2.75mil)?
