johnqt isnt only for the igl role, its also for the sentinel role. pancada has looked meh all season because he has been on senti. he always looks good on viper and thats for a reason. being an igl who can bring more strats and all that to the team plus being able to fix their role issues is a good pick up.
EG works so well not only because they have good shooters, but because of their great util usage and on the spot decisions. yes im sure potter has a lot to do with that but so does boostio.
I am not opposed to more/different coaching staff.
