[4e] Rogues, Rangers, and Warlocks

[skywalker]

As to the rogue question, they still have to be concealed/covered. I personally wouldn't allow allies to count for that,

What if the rogue is a halfling and the ally is a massive dragonborn?

To the original discussion, I've not seen a ranger(nor read its powers, really) but as has been said, the warlock does good damage every turn while the rogue waits and then absolutely owns with CA.

EDIT: Jax, who was complaining?
