... and just end up dying way too much. I just played a match where my teammate went 14-27. Seriously, how do you die 27 times in a team slayer game where all 4 people on your team stay till the end. I was at 12-5 when he lost it for us.
If you die more than 25 times in a game where all your teammates stay till the end, you need to turn off your game and re-assess your strategy.
I understand that people have a bad day sometimes, I do a lot as I'm a very hit or miss player, but I am at least good at spotting when the other team is out-performing me, and I start playing more carefully, and sticking with teammates.
If you know that the other team is taking you out most times you meet, you should be able to recognize it and stop rushing in for a chance to "redeem yourself".
