Game Mechanics: PVP 8+/-8 system NOT WORKING properly

[Kungen]

I've seen it happen several times today while PVPing on the beta. I'm a level 44 wizard first of all.

1) So I went to Lguk to do some PVP. There was a group of 3 people, Sloris a level 40 mage, Cwall 35 shaman and Samwise a level 30 druid.

So I attack the level 40 mage and then both Cwall and Samwise came in my range and they both could attack me. But I couldn't attack them back and I assume it's not suppose to be like that? You're suppose to be able to attack anyone who attack you correct?

Later on in Sol A this monk named Rexx could attack me, but I could not attack him back? Made no sense at all. Same thing happened to Fratboy in Lavastorm, this cleric called Katyperry could dispell and attack him but he could not attack her back.

I'm assume this is a bug since it makes no sense at all that low level ppl can attack you while you cant do anything to defend yourself.
