I don't have the rep to neg anyone...so can;t speak for whoever bonked you...but I submit you might have caught a neg from two things you may not be thinking of...and neither is for posting alleged "truths" about wardens:
1) you are actually wrong, since wardens have always generated more aggro than guards...plainly and simply. Guards have a better force taunt or two (for now), and can manipulate PERCEIVED threat via threat stance and engage...but flag behind a wardens ability to genuinely generate threat in the first instance.
2) I believe it was your own lack of understanding the indicated disctinction, that then had you directing the next three phrases to a poster who did understand the distinction...and the obvious antagonostic style that you exhibited in so doing, that probably got you the rep-neg.
So...maybe be more civil in competing class forums, and actually post accurate info, and perhaps you will catch less flak.
PS - (who am I kidding...I have caught plenty of flak here too, even when trying to help guards...its a tough forum)
