You have every right to be Mad. And. Angry.
Feelings are real.
However just as the guy in the T-30 Had No Right to attempt to push you into a Lake, You had no right to shoot him, either.
Trust a fellow team killer on this one.
The last time i team killed someone I was in a Tiger 2. I had a zoom mod used and i was shooting into a fat cluster of tanks.
Sadly i was zoomed in so close to hit weak spots (i had the 88 mounted not the 105) that i didnt see the colored outlines.
And so tunnel visioned that i was paying no attention to chat.
So after wondering just how lucky i was to set that other Tiger 2 on fire
then i was like what the hell im blue?
now my tank is locked up?
Oh [edited]me running!
After the battle the loading screen sez im banned.
Because i killed a green tank.
not a little paint trading getting out of the spawn.
not some yahoo running in front of my gun while im blazing away.
Not a little bent fenders from pushing that slow [edited]AT-2 to the fight with my T1 Heavy. (a valid tactic i highly recommend btw)
In point of fact i had to do a crapton of damage to make it happen. (Tiger 2 has 1600 HP and i did most of that damage)
I got Banned.
But because this is the first time in god knows how long since this happened.
I was only banned for like 1-4 hours. I forget how long it was.
Which makes me wonder how you triggered a ban after "only three shots" with a T-37.
Maybe that Team_Killing sunovabitch was pushing your camping scout [edited]into a lake because you weren't suicide scouting.
Maybe your three shots you fired as you met your watery doom ammo racked/burned to the ground that [edited]?
(which if you had im sure you would have mentioned by now)
It still doesnt matter. you killed a friendly. Just like I did.
So by the time you see this Im sure your ban is lifted.
Maybe if you dont have the time to address your anger problems ...
then get a mod that prevents firing at friendlies.
(solo's mod pack has this and much more Dont worry it lets you kill Blues just fine.)
That way you never get banned for TKing again.
