Question about melee PvP

[Planchard]

I played on the PvP server on live but I think only got up to lvl 9 so I never encountered PvP. I encountered my first PvP fight last night against a twinked rogue. Of course since I'm a noob cleric, he targets me first in an attempt to kill me.

My first thought was just tank him and allow my group to kill him. Well he wasn't dying and I was running low on mana so I decided to gate. Got some mana back went to zone line and my group started to zone out. The twink is back but focusing on another target. The twink sees me again and starts beating on me again. I knew it was pointless to just let him beat on me so I tried something else. I just held the RMB and strafed in a NASCAR oval and he was never able to hit me. I also didn't have SoW at the time.

At first I thought it was funny but then started to worry since I'm playing a monk with a shaman friend. Is this all it takes to make a melee be useless in PvP or did the twink just get juked by a noob?
