I can get upset some times for example few nights a go i got my LEANDER out stock and new comander and i get to see rank 4 ships and rank 8 in the same fight day after day.
2 ideas that i have might fix this and make the game a bit more even.
Firs change the MM so it will only filter 10-9-8 in top then 9-8-7 and so (Can even name this game play type some thing cool and fitting )
The other idea is to use your system of raked battle for ranks 4-10
on those both have no limit on how long players need to wait to get in to a fight but on the same time run your system
