Hello, I am new to the forum and would like to respond to this.
I absolutely agree that the penalty system is not working fairly.
WoW is a great game but every day I get sick of undeserved penalties, allies that go to your torpedoes on purpose or lie down in front of your boat while you are shooting with a zoomed-in image and focused on the enemy, so you shoot unknowingly on an ally but that doesn't mean it's me.
Like, as I understand it, the penalty system is meant to prevent allies from shooting at each other. Then it is better to develop in such a way that, proportionally, the damage that you have sustained from an attacking ally, that is merit from that particular battle and according to ratio for the damage done to you. The attacking ally gets that battle so less xp and so on because you have to complete the battle with less HP. Hopefully these noobs who often just do something then start thinking because they earn less.
I really hope that something will be done about this, playing Wow is fun, but every time and sometimes every day getting rid of penalties, I now have a hate about it.
