The alternative of creating semi-autonomous stationary-pet turrets would be a lot easier to get working, but thematically doesn't quite fit (although it might work for a sub-class or paragon path or something).

Getting the "deals with many enemies" and the "cripples the enemy" roles to mesh is a little tricky to do with a martial character.
I'd a weapon throwing factor to this, like using a rope as a lasso or for bolas to restrain. The roman pilum was used similarly, to get stuck in a target and interfere with their movement, so there could be abilities using throw weapons like that. And if they depend on clean lines of attack, these might help make up the difference of how much the enemy can maneuver.

Maybe call the class "skirmisher," and use "ninja" and "trapper" for paragon paths?
