4e mark fights?

[Kurald Galain]

For the ones playing 4e.. Has there been any huge fights oer who gets to mark or hae things gone smoothly?

A huge fight, well, no. I've seen a few cases of e.g. a paladin and swordmage overriding each other's mark for a while, yes. Overall it's no big deal, and usually they decide together which of the two "mark reprisals" is most useful in the situation at hand.
