I use a form of player roles. Regular player roles are VERY flawed. I have 4 role ratings for Off, De, BH, and Reb. I have 2 different DEs (1-2-3 and 4-5) and 4 different OFFs which I take the max of (Slasher (Ath, Sp, BH), LP (LP and Ath), Per (Lots of PE, BH, Speed), Speed/Slashing Shooter (Pe, BH, Sp)). I have 1 rating for Reb and 1 for BH. I will then eyeball those 4 numbers and stamina to figure out how much I want a player. That being said, I will also eyeball a player's ratings.
