I don't know that an absolutely new player should really be too familiar with relics. If you aren't committed to either light side or dark side, you may not even get a relic to use until level 50, so you might not really be familiar with them.
And how the hell are you supposed to now if someone is THAT bad (and yes, I'll call it bad since it really doesn't take much to simply read the info on the item)? Most people can manage a simple task like that, so it IS more than fair to assume that anyone rolling on what they shouldn't is a ninja (and they are - they're just not aware of it). Like I've said multiple times though
- IF it turns out they made a mistake and fixes it I'll forget about it. This isn't a court of law, so "innocent until proven otherwise" doesn't apply.
