I'm more into thinking that Team Secret is likely to fill the slot of Nisha either by Topson or by Boom, an ex-mid player of Gaimin Gladiators.
There's a twitter post that mentioned Secret.Topson and his wife replied with a no so we might see Boom or another mid player.
On the other hand, a lot of people are saying that Nisha would move to Team Liquid which is possible since they said that he nearly joined before deciding to stay with Team Secret.
With what I know of, micke is going to be switching roles and practicing the pos 1 role in the pub games
Yup, micke can easily switch to the carry role since he used to play carry back then during the Alliance days.
