I dont understand very well your problem, but if I understand correctly, you can report people for kick you for no reason and also for insulting you.
If the party is incomplete, there are no penalty for leaving a party.
When is someone is new in a duty, I can completely understand some kind of mistakes could happen and tolerate it, no problem. It is desnecessary harass people, I think the only thing that really trigger in newbies are when they dont listen me: "hey, I will grab a coffee rq, brb" and the tankers pulled anyway, I feel disrespected and not necessary (I'm a DPS). Of course I will not insulte people, but I will happily press "leave" depending on the instance.
Call my attention you mention dungeons, there is no point to this kind of behavior in this kind of duty (being salt and leave). I defend your playstyle for fun, I just think you were very unlucky with the kind of people you find in these dungeons.
