What you are suggesting Korgov is a huge amount of data being able to change in a tremendously volatile fashion… Imo it is a good idea but it can only be done on paper.
There is no solution to the bad matchups apart from redesigning how they are being decided. If not a radical redesign (which will never happen) then some heavy tweaks which take into account a shorter period of time when calculating the servers score while still keeping some sort of notion of who is actually overachieving .
In order to do that, you will also need to take into account in a servers rating stuff like:
Average WvW attendance per server in terms of hours per player.
Average WvW attendance per server in terms of population numbers.
Total population per server (needs to be taken into account or else low wvw partitipation/high populace servers will be able to call on thier PvE ppl and ruin any matchup at any time).
Pretty complex stuff when you have to express all of it (and what was previously taken into account) as a single function that quantifies server power both in relative short-term and long-term.
PS. Personally i wouldn’t hold my breath for any kind of important changes to the matchup engine.
