You almost have right idea, I'll help you out.
Game 1
Ashe [00:14:22] of f****** course.
Totally fine, ranting is protected in the summoners code.
Ashe [00:18:15] STOP F****** DYING
Ashe [00:18:17] GET THE F*** BACK
You crossed some people lines, not mine. You didn't INSULT a person, but you did cuss at them.
Ashe [All] [00:22:31] I'm the best on this team.
Mordekaiser [All] [00:22:39] not even close
Ashe [All] [00:22:46] prove it with score then death.
^ Then you went off the rails and became a jerk. Stay away from ALL chat unless you have something nice to say to the other team.
Game #2
Nothing
Game #3
Tristana [All] [00:05:57] stop trying to be superman or the flash with ur uber run
Tristana [00:11:05] f****** *****.
Tristana [00:13:01] kat
Tristana [00:13:03] when I pinged.
Tristana [00:17:29] TRUNDLE
Tristana [00:17:32] WORK WITH THE ******* TEAM
Again, with the perceived cussing AT the team and the members of it. No no
Tristana [All] [00:24:36] oh wait, had trundle came earlier, we could have killed.
Tristana [All] [00:24:57] kat my score is low because you steal all the kills in team fights mostly, because of your f****** ability speed spam
Tristana [All] [00:25:03] and because I get focused first in every team fight
Tristana [All] [00:25:14] even if I run with double speed quints, they chase down so fast it's ****ing bull****.
Here you are being super jerk again RANTING to the other team about yours...
Game#4
Caps hell... no more needs to be said
Game #5
Nothing
You seriously need to modify your behavior or you're going to get in serious trouble. Most of us have had a bad day or a few bad games.
It's real simple if you are talking to your team or the other team EVERYTHING you say MUST be constructive. There is NO other legitimate purpose to talk to ANYONE else if you aren't doing that. IF you are frustrated and believe me I get frustrated a lot too, RANT at nothing or at least take ownership. "We are sucking so bad right now BECAUSE" <----- now offer what is going wrong and what to do to fix it. You took ownership right there, you are trying to fix it. I would pardon that, some others wrongly wouldn't and would claim it is negative... frustration is NOT negative. Harming others is. Some judges don't get that.
Anyways, I hope that clears it up for ya. If you had 1 game out of 5... some cut you slack. 3 out of 5... punish. You were overwhelmingly punished... that means everyone.
