Best 10 out of all is at least better than the first one they did (counting all).
But the best was would be the average from the whole time. So all matches are count.
But what we will see this weeking, are some damage dealer over kill

. ripping the armor instead of killing to get out more damage done. A full weight on damage with only 5 points for a kill, means heavy damage without any smart aiming.
You get more points when you deal 1200 damage without any kills instead of 1000 damage with 8 kills, surviving and win.
It will be a really interessting weekend

and we might see some strange damage races with insulting why some are killed and still have armor

.
Hell, i can already see it. 16 assault standing against each other and fighting for every points of damage dealt. Even teamkills will be possible to "remove" competition...
Calculated max from the matches i saw so far (max damage around 1100) would mean max points of 11,900. i will not be surprissed when we see some with more than 12,000 points this weekend.
I guess i will play light mech, and just try to cap.
