Classes with no way to interupt someone at range are the following; paladins,to a lesser extent druids,priest unless they're shadow.
OH BUT WARRIORS CANT RANGE ITNERUPT YOU SAY? if it disrupts your burst in a way that reck us totally wasted,and the enemy paladin is somehow not CCed while you burst,then you can heroic leap pummel him/throwdown him/fear him and charge back on your target. It's been done and its not overly complicated.
Erm...that has nothing to do with anything?
I never said it wasn't counterable (or did you really think I was saying that?).
