No, they are not going to spend even close to the amount required for buying out Valde on any future players. Look at their roster changes since the kicked karrigan, who have they paid for? Adren, Neo and Kio was all free agents. The organization have spend alot to buy out rain, niko, olof, guardian and thats the super team they paid for. They are not going to buy anybody in that price range anymore, and valde might just be even more expensive.
Other than, even if they did have the money. Valde wouldnt go to Faze, he has his own team in North where everybody backs him up, some of the best facilities and he gets paid way more than he wouldi n Faze.
There are multiple reasons why this wont happend, making it completely unrealistic
