they split up because it didn't work anymore..
long story short:
byali and snax got carried away in the head and they were toxic to the other 3 legends when they were not performing well, eventually they persuaded neo to get rid of taz because they said he is the weak link, taz was actually a weak link because he lost motivation and confidence from all the toxic shit from snax and byali. Neo finally made the worst decision of his life and they benched taz, then they got even worse than they were before leading to another backstab from snax leaving the team thinking he is wasting his talent with washed up pros, little did he know he only achieved anything in this game because of his extremely experienced legendary teammates. Yes, lot of times sheer experience has a better value than skills. so they got rid of neo and pasha as well and built a new team with young players. I wonder if snax and byali ever think about what they ruined.. and that they will never have a team as good as the one they destroyed themselves.
