How come i can be attacked during boss events by players who are over 4 levels higher than me? i thought if u were under 3 from them you could not be attacked.

i'm 2nd in realm so does this make a difference? im only lvl 93 yet am being hit regularly by player lvl 106 or better. can someone please explain how thsi works please. i wouldnt be upset about it if tthey too had boss form hapening at teh time, but the cheeky buggers dont so im able to be picked off fairly easily for them.

cheers
