Are you sure it's not the fact that your stats suggest that you spent more than 70% of your time in a Titan in TF1? Your distribution is totally different in TF2, you only get about half of your kills in the Titan (which is quite a lot). You have 2200 as pilot, 1800 in titan, I have 5564 as pilot, 1816 as Titan. Your stats appear to benefit astronomically from your Tone gameplay.
Your stats are really odd generally to be honest, super high KDR but modest win/loss. I would have thought your team would have won more if you are getting so many kills, it always seems super easy to carry in attrition, pilot vs pilot and bounty hunter. I tend to leave my Titan quite a bit to play the objective which probably accounts for the higher win / loss and MVP rate, but lower KDR.
Your TF1 stats are insane though. The only time I've ever had or seen stats like that was on Starhawk, which actually had a sort of similar system with hawks just decimating pilots on the ground. Quite a lot of the top 100 or so pilots had 10+ KDRs on that game, I guess it was the high skill ceiling, unbalanced nature of the game and lack of good tutorials (in Starhawks case).
