Game Mechanics: Unable to defend self in PvP

[Greenkrak]

Had the same issue, obviously the pvp dynamic mechanics are screwy right now but just bringing it up.

I continually see low level players in my range (orange name) at lvl 46 in city zones and in crushbone as well, and am freely able to attack them.

However some peoples names will show as yellow, aslo out of my range (he was lvl 30ish) but he could freely attack me while i attacked back and it says the character is protected so i am unable to defend myself.
