something small, and a personal opine.
when a >2000 player randomly (TDM/DM etc) matches up with a lower tier type, join and treat as an epic chance to be a teacher of Hawken.
i matched in a 2013 smurf account with Dave,tonight and enjoyed every second of it.
DeathMatch. encredible. i hadnt that much fun ina looooong time.
he left before time out. cant' blame him, it would have Killed his mmr.
but Hawken needs to get a match/room where this can happen with no ill effects to MMR, simply because it's so fun.
And you give valuable skills and help to folks much newer/lower ranked than you.
Just an idea.
