Up until now the ranking formula has been quite appropriate for the environment it is made for (CCL), starting the scaling use of win% at 50% of total and rising to 100% (and slightly beyond) over a set number of games.
The problem I foresee is that as of LE we have tier 3 teams whose win rates are expected to be significantly below 50%. The danger with that is that we may see Gobling, Ogre, and Halfling teams with a perfect but very short record placing well above the more realistic records of better coaches who have played significantly more games.
So, while this is a bit of an edge case that is only likely to affect tier 3 rosters, I'm suggesting the base multiplier be shifted from 50% or whatever it's at, down to around 30%, maybe even 20%. That would keep the better performing, higher number of games played coaches at the front of the pack rather than low games played perfect record teams.
