i thought the same but i wouldnt recommend going lower than 1.7
yes niko is an exception, but he has 0,00001% elite genetics.
against good players(high level elo faceit) you would suck hard, cuz they know how to hold crossfires, execute fast with right nade usage, peek wide.
there is a reason why almost every pro is around 1.7-2.5 sens
if 1.4 would be a good sens many pros would use it, but they dont. just few exceptions.
