With the new and "improved" matchmaking, my last couple of matches have 9 out of 10 been onesided slaughterfests, with one side losing 0-1 mech at most.
Take this screenshot for example...

While certainly not the rule, such onesided matches are not rare. I'd say around 25% of my matches are 8:0 stomps. Interesting is, that it seems to get worse, the longer I play with the ELO system in place.
I'm also drifting away from a 50/50 average, with my win/lose ratio falling below 1 and my kill/death ratio climbing towards the 2. Was ELO silently disabled or is it just that bad?
Unfortunatly I did not grab a screenshot of the worst match in the history of MWO. The worst player on the winning team had around 200 damage done, which was 2 times the damage of the entire losing team combined. I wish I would have frapsed it...
