This "patience" applies both ways.
Think of it this way: The Admin turns around and witnesses you deliberately attacking someone. You say he started it, he says you started it. The Admin has only seen you attack and not him... Which side will be chosen more often then not?
For future reference, always report using "i" chat, never retaliate (for any reason, period), and take screenshots/recordings and post them in this sub-forum.
Revenge Teamwounding and Revenge Teamkilling is against the rules, not only because it is often impossible to tell "who started it" on word-of-mouth alone, but also because Vigilante behavior quickly causes the entire server to fall into absolute chaos (and then I ask Espu to mass-ban all NA).
