Okay, so - FaZe w/ karrigan when karrigan was calling - NiKo was decent, 23 kills normally, rain was struggling, olof was as good as NiKo, same goes for GuardiaN, karrigan was karrigan.
FaZe w/ karrigan when NiKo was calling - NiKo was 30 bombing, rain still rain, karrigan still karrigan, olof was suddenly on rain's level and GuardiaN wasn't as good as he used to be either.
FaZe w/ AdreN - same as the 1 above except AdreN is decent ans there is no karrigan.
And do u honestly think AdreN could call in English? He is from kazakhstan and he spoke russian throughout his whole carreer. He definetely couldn't start calling at a professional level in a few weeks and if not at a professional level, FaZe wouldn't even let him.
