Map kiting in Crossworlds

[feloniousmonk]

I played AP on Hard with a Warrior, which turned out to get really easy in the second half of the game.

So I thought I'd try my hand at Orcs on the March with a Mage on Impossible. I've been unable to successfully kite a map guard, except the one on the coast in Rusty Anchor where I was able jump in my ship. The ones on land seem to have a boundary that they refuse to cross.

It could be that they changed the behavior for the mobs guarding maps, or that I am just not very good at kiting. Can a pro kiter verify whether this has changed?
