Yeah, it'd be interesting to go through all the martial powers and rejigger them to remove such things. For example, you could change inspiring word to an interrupt, not usable on someone who is unconscious or deafened, and it could be 'more realistic'.
Which is why I figure when a paladin does it - stuff like Knightly Intercession that effect: pulls 10, it's a lot more palatable to those who dislike Martial doing that kinda stuff. Tough line to walk on making sure Martial has all the right tools and is cool, with it not being allowed to do certain other things, of course, but should be doable.
I think that Martial Powers should do more Pushes, more Knock Prone, more certain types of conditions (like Daze or Stun), and virtually no Heals and fewer Buffs and even fewer Debuffs to some extent (except for Leader classes).
It kind of drives me crazy that a Druid really has to search to find a Healing power and nearly all of them are Dailies, but Warlords get them right and left.
