Running and ..., are they better?

Sometimes I ran off, just to safe my butt. And I'm being hit. That is no big deal, after all I was fighting and chasing stuff and now I'm being chased. Ok, but the nearest guy (the nearest monster, foe, I am talking about pve) is 1/4, say 1/3 outside my aggro-circle, at best the distance range of a long bow.
What is hitting me? I am running, behind me is a line of red dots, not close and certainly not closing in on me, yet they can fire at me or hitting me with a spell. How do the do that? I have a ranger. When I want to hit something that is running of, I first have to close in on the target, because I cannot fire and run at the same time, and when I stop and fire, my target wins distance on me. The same counts for spellcasting. Is this system lag, or gives the AI an advantage to the enemy?

yeah, they can run and cast at the same time, don't seem to lose energy and can hit targets through walls or well out of their aggro range. Its unfair but its just how it is.

Wahhhhh Mommy the A.I is uber leet and im not........yeah thats how it is i hate it too............especially when char blade warriors owned me.

Not to flame, or sound negative, although I might: I like the idea of them being able to damage you on the run, see me, I'm more of a "All or nothing" type of man, if we get swarmed, unless i'm the last one alive, I stay to the bitter end! YARR =)

But the AI, Imho, is pretty decent with spellcasting on the run. As for melee, make sure those red dots following you aint casters/archers and post again if they still hit you. <Aside from giants and or melee with projectiles>..if you're still being hit, It's a glitch.

I run very successfully when I want to, and those red dots do damage, but my 3-pip regen Mending successfully rules out any projectile damage..but <DAMN you Pinesouls! Damn you Mesmer Enemies! And especially together!> Nothing like being cripple from a trap, and for 14 seconds having a -5 degen hp rate..ughh..nightmares.

Anyways, thats my 2 cents.
