Ok, in arathi basin i just discovered something, if u have not noticed there are some rats in farm, it is always there, but when an alliance tries to sap me and try to take the flag,yes it works for them, but after i killed the rogue, i recapped it and i knew he was going for another sap, so what i did was "I PLACED A HARMLESS DOT ON A RAT AND IT MADE ME GO ON COMBAT" SO that Means U are Invulnerable to
-Sap
-Blind
-Seduce
this is what i just found out today.
without insignia of the alliance
