#4 is an interesting idea, it is like faze with two powerhouses in niko and coldzera on different bomb sites, I like how coldzera plays on blue box and niko is solid and has support from rain and utilises the team well
Pretty sure that at this point any roster change is going to make 100T much much worse than they are atm. I would guess that they're gonna go with this lineup until it stops working completely and then disband.
The change would depend on whether you want to improve lan or online results. Grat has been doing really well online, but on lan he’s been ass for the longest time. I’d say -grat +sico (I know it’s not rly realistic) would be the best possible move if you wanted to keep it in Oceania and improve in the long run.
