Oi. I'll try to be more clear, now that I have a little more info. Here's the chronology as I understand it.
(1) Approximately five weeks ago, the pregen character sheets were printed with soon to be incorrect mechanics for the Paladin.
(2) The incorrect mechanics involved the Paladin using the marking ability, something also available to (as far as we know at this point) the Fighter, Rogue, Range and Warlock. Sure they call it something different, but it's basically the same thing.
(3) The reason for the needed change (without taking into account flavor issues related to cowardly Paladins) is that the Paladin's mark did damage if the creature doesn't attack the Paladin, ultimately creating a situation where a Paladin can kill just about anything simply by marking it and then making a quick getaway.
So, at this late stage of the game (four months to release and who knows how soon to printing) they had either:
(1) Only recently added this ability to the Paladin's suite of powers and just as quickly modified it.
Or
(2) Had only recently realized that a 1st level power that should at this point be thoroughly play-tested was suddenly discovered to have what seems like a pretty obvious glitch.
Like I said. It concerns me. They've been working on this for two years and they're adding glitchy powers to classes this late in the game?
