No, Niko is a great player and is worth every penny. There has been a lot worse transfers.
You could argue about that -aleksiB was the worst move, same as -xseven +VAC banned player, who isnt that great prodigy that everyone thought of.
Same goes for old after Boston Major C9 roster moves, most of them were pretty bad and so on
I mean, NiKo win G2 mirage. The problem was the whole team today, don't understand why NiKo is worst transfer in history, where there are WAY MORE worst transfers. But guess you can't check it yourself.
