I think a much more elegant solution is for people to get a ranking based on how good they are, K/D ratio, amount of damage done, amount taken, accuracy with weapon, average rank in WP at end of match, modify these numbers for their favorite weapon, vehicle, suit types, and skill points and come up some final number that determines how "good" of a player you are.

Based on this number, matchmaking should try to assign 2 teams each with similar sums of the player's number. In other words, it's ok to have good and bad players, high and low skill point players on the battlefield as long as they're in roughly equal proportions for each team. This should keep the matches close and check pub stoming with having other people on your side that can counter them.

Additionally, pubstomping should be countered by making proto gear unaffordable to be used profitably. You should have to save up ISK in the pub matches using economical fits to be able to afford proto for important matches (or be willing to take steep losses to your wallet if you just want to have fun in the best gear in unimportant matches). Risk/reward.

AFKing also needs to be addressed for this system to work (since it will make good players appear artificially weaker than they are). This should be easy to track: how much damage to enemy players have they done? Are they looking left/right/up/down? Are they in close proximity to an objective? Are they gaining WP?

This data will look very different for a player just starting out as a sniper on the red-line with a crappy rifle, lots of sway, and not enough DPS to get kills/assists, and someone past the red-line crouch-walking into a mountain with a rubber-band on the joystick.
