Not at all, you're fine. Listen to me son, if you come out on top each game and your teammates are just feeding kills to the opposing team.. it is OK , to send them a message telling them they suck. It might get you banned for a few days for a few days but it's worth it :)
Uh no, thats not ok. Thats being an -Yoink-. You and the OP must take the game too seriously.
You sound like you take it too seriously.....
Yea OP, you sound like the person who would play a match for example, lose by a kill or two and be pissed about it for days. Instead of saying "Well that was fun, we came really close. Next match I'm totally getting that win" Someone who takes the game too seriously would be cursing out their team through their mics, sending hate messages to the enemy team, throwing controllers across the room. Actually, there is probably a bunch of youtube videos on this. You should look some up and see if you share any of their behaviors.
