I understand what your trying for with this rating system but it don’t work…
if you win matches, you earn points…
if you lose matches, you lose points…
thats great, then call it ‘Competivie TEAM Skill Rating’…
but from what I can tell, this is a personal, individual rating?! Right?! So why am I losing points when I go 20-5 in a match & top the scoreboard?!..
Now if your telling me I’m losing points cause I lost a match because of the random team mates I got matched up with turned out to suck?! Then that’s not fare?!
I think if your going to continue with this style of Skill Rating… Then please assign it to individual personal performance… Not a team win or lose system…
something like:
For every 3 kills = 1 point
For every consecutive/double kill = 1 point
For every consecutive/triple kill = 1 point
For staying alive for 30 seconds = 1 point
For every 5 medals earned = 1 point
So on an so on…Then by the end of the match, all the points would be added together an put toward your ‘Competitive Skill Rating’
I think that makes more sence…
Apart from this small issue… I’m liking what you guys have done with Halo5 so far… 
So what do you all think?
