They could go for a genuine 6 man roster. If they had to kick someone it's a difficult choice.
If you kick Lucas then you probably lose hen1 too as they want to play together
(rip hen1 in furia, that was sick while it lasted)
I don't think fer is a part of the roster, although I could be wrong as I don't keep up to date with roster moves like these.
Either way, you gotta have kNg and V$M in the team, and if you want one of the twins, you're stuck with both of them as mentioned before.
TLDR: I have no clue :D
