I play Kill Confirmed almost exclusively and I'm now purposely avoiding tags like the plague to lower my SPM to see if it stops putting me up against full parties and "try hards" every single match because I play COD to relax, not to have intense competition every single match against parties while I'm running solo. It's not really working though. My SPM is down to about 350 and I'm still getting matched up against mostly full parties.
Sort of confirm. Yeah, K/Dr means the most in TDM, FFA and KC, but it has meaning in other modes. Those modes are:
SnD (since that is both a kill based and objective based game) HQ (if you have the HQ, you don't respawn when you die) CTF (because of the long respawn delay; if you die a lot, you leave your flag vulnerable)
