well sins imho are underpreforming in general.. true
but solorating is just based on statistics.. and statistically.. me and dog have 3 legs...
so pls stop BS that solorating is a good way to measure someone's skill, becasue simply it isn't
this is due to various variables which need to be taken into account and are totaly independent = meaning you as a player can not really affect them..
same may implay to group rating.. but there are far less variables which makes it far more accurate..
that being said.. imho best way to evaluate someone's skill is simply to play with them.
you can't play with everyone... so only thing that is left is this rating system which just shows approximate skill..
better this than nothing i guess..
if you really believe tha this is accurate, please do.. you can believe what you want really
but trying to convince somebody that they are wrong being wrong yourself is just bad..
