SunPayus wouldn't fit within Liquid at all and it would be a failed experiment. Neither would Mantuu. Wanna know why?
Because Liquid as a team refuse to focus on their awper as a play maker and would rather their riflers to make the plays and do the work, with oSee as a solid base to hold that lead after the rifles get it. The problem is, that doesn't work. Especially not when you have your awper throwing nades rather than holding an angle. No EU awper would fit in Liquid not only would there be a greater language and chemistry barrier but their full talents would be completely wasted. But go off king.
Wiz is more consistent with holding angles, oSee was way more comfortable with flicking and showing off in Tier2 NA and that style doesn't work in Tier1 unless you're one of the greatest like S1mple or Device.
