Possibly a Idiot.
Example of this near impossibility? Fighters only have 1 opportunity or immediate interrupt, and same for wardens.
That's all you need for one enemy, and far more than the paladin gets from their mark.
The swordmage would like to have a word with you.
Maybe I wasn't clear enough, but the quote in that post mentioned both the (shielding) swordmage and the paladin, because they both have automatic marks. The "other defenders" in this case would be the fighter and the warden.
