Me and some friends have created a discord server based around the concept of tier lower than PU, often called FU. When I made the initial tier list. I noticed something odd, Type: Null was low enough in usage to be allowed. I find this odd since it is currently A- in the PU vr. I know Viability ranking does not = usage in any way, but i find it weird a mon so viable is so uncommon. I was wondering if anyone here knew of a reason why this might be?
