Its not really SBMM. Think of it this way, each person has a point based their skill from 1-15. 15 being highly skilled and 1 being lowly skilled. Say youre a 15 and the other team adds up to 24 (Each person has a skill of 4). The rest of your team then is going to have an average of around 2. This is why its so unbalanced because it really only balances the team instead of the players. At least this is how it seems to me.
