Played 4 games today in co-op TDM, 1 with another player, and got my butt handed to me in every one; I squeezed out a 40-39 in the last game, but lucky shot was all that was.
And, yes they gang-attacked, assaulted sniper posts, Flanked - FLANKED! - and seemed generally buffed up, relentless dodge, those patented, backwards/upwards leaps, with both barrels blazing, no-miss scouts (Hate Them), different attack patterns not down the standard lanes, etc., etc.
As for talent matching... I try every once in a while to DM or TDM, but inevitably am outclassed by players that somehow score three times as fast and high as me.
Also, I recently played in a game where my team (all human) won with everyone scoring between 100-200 pts; then a game very similar later on, two players blew in, scored 300+ points and left - funny thing, Everyone scored over 300 that round - then we went back to scoring 100... tell me that wasn't a hack, which made me think what the leaderboard reflects ...
Tell you what I WOULD like to see change: the bonus free mechs - I'm up to my muffler in Bruisers and Raiders!
So, yes, I see I have to kick my game up a notch if I ever want to win again.
(p.s. They were great matches, and I was caught off-guard by their upgraded talent, but great matches!)
