Now that I've been Admining on Siege, I've modified my opinion.
5/5 is good for Siege. Don't change it there.
3/3 is good for Battle. Battle does need its threshold for kick lowered.
Completely agree with that.
But... i'd also like, for battle, the possibility to directly add 2 (instead of the usual one) if you get teamkilled. Thing is, at the moment, loosing 1 hp or your entire health bar in one hit (or one kick making you fall down) result in the same unique -1. I'd love to see it based on the percentage of health lost.
Some people find it funny to one-hit kill you, knowing that they'll get only 1 "report" anyway, and that, SINCE they get the blame, the other players don't do anything about it.
"Well, you did blame him, so he got his punishment."
I usually never go beyond 2 reports, and... kind of really deserve let's say 3/4th of them. Playing stupid, etc... And we'll say that's how it is for a major part of the players, unless they're even better and rarely get even one report.
So this change will not hinder the occasional teamhitters, but will prevent the intentional ones from doing them too often.
Cause let's face it, thanks to this good "report system" added, there's unfortunately a lack of severity from admins when considering teamattacks and teamkilling. The usual "Well, you already reported him, if he don't behave, he'll be kicked automatically." Wich is not right, imo.
