Doesn’t that make it similar to Reach, in that you could rank up more if you individually perform better? You said you don’t weight kills towards your MMR, but then from the next post it sounds like performance does factor. So i have a better chance of individually ranking up my MMR by taking rockets and getting more kills, than I do by sitting back and holding a spawn point while my teammate takes rockets (assuming we win either way), right? Am I misunderstanding? The example above even goes as far to say if you play very well, individually you could go up despite a loss (because your team as a whole goes down). To me that sounds like it opens the can of worms that the reach system did (I understand this is much more accurate than the reach system, but once players realize that individual performance matters after placement matches, it could lead to more solo performances instead of team play.. or maybe h5 has always been this way and I never realized..). Just my two cents.
The accuracy makes a huge difference though, and is why in Gears 4, this hasn't caused any issues.
The thing is, if you are playing with near equally-skilled players, grabbing rockets isn't going to get you enough more kills to make a difference.
If you are a better player, then maybe you could, but you're better anyways, and that's not changing the update.
If you're a worse player, you're unlikely to make an impact doing that.
So as long as the balance between wins and the rest is right, we're good.
Not to mention the fact that too much selfish play leads to losses, and leads to the system adapting to downweight that behavior anyways. So either way, still gotta win.
