Yeah I had this shit happen a few times when I tried the beta. But shit like this is infinitely better than killing that buffalo, being 1/2 health and here comes Lv60 Johhny PVP to wreck your shit and tea bag your ass. If Im going to PVP it will be on my terms in an environment that is semi fair and semi balanced.
Hate on them all you want, this is why blizzards creation of the battlegrounds was so great for these games. It let you choose when you wanted to PVP in the different modes they had. You actually had goals and scoring within the game type, and the interactions were more balanced than encounters out in the wild speaking numbers wise. Of course you always had the gear balance issues and class balance issues, but thats a different discussion.
