Team Secret's FB page posted that within just a few moments, they're going to have an announcement and I think that's the replacement of Nisha and it all escalated too quick.
Too sad that Nisha really has to go after 4 years but I think there's a better opportunity that has been offered to him. If Nisha goes to Team Liquid then he's still with a good team.
Edit: Team Secret already announced Boom as their mid player. -->

https://teamsecret.gg/blogs/dota-2/welcome-boomI just hope Boom will be able to fill up the shoe that Nisha left in Team Secret. Like you said, 4 years is a long time playing with the team. There will be a lot of adjustments especially for Boom to fit the gaming style of the 4 Team Secret left in the team.
Is it confirmed that Nisha will be playing for team Liquid? First it was Topson, now Nisha. Both players are mid laners so Micke has to adjust to become the offlaner or Nisha will transition to carry offlaner. Whateve position he transition to, hopefully he fits well to his new team.
