i need help, please..

people I am new to the game, and while I was upgrading my dk, more or less lvl 65 I was doing a dungeon, and a dk tank and I dk dps had a friction, we didn't want the msm item, the item was based on str and stm, but I didn't know about a 'passive bonus' of defense that he might have, I say maybe because if the guy reported to me that item might have, but even if it does have a small attribute, a new player will not know that, n you will know that you can 'need' something that will report you and you will not play for days because of that, I am very upset because the guy said with conviction that I would be banned, I am in the hype in the game because I am enjoying it a lot, I even brought my friends to the game and we are already in a guild, we are about 20 people, I know we are number and 20 more or 20 less does not make any difference to the owner of the server, more me I was wondering if there's a way to get my ban? i want to upload my little doll i am enjoying the game and i want to play it ..
please..
a new player will take a ban without knowing why because he had the option of 'need' if you can't get the item because he would have the option of need ??
someone help me please

It clearly states "Equip: Increases defense rating by XXX". You couldn't miss that.
Yes, you could get banned if you needed item that's not for your class/specialization. You are DPS and you needed a tank item. If you didn't get it you probably won't be banned, if you however got the item and if he reported you you'll get banned for "ninja looting in dungeons".
If you could've seen the item has strength and stamina then you could've just as easily seen the green letters beneath it saying it has defensive stats.
The first ban is 5 days.
