I'm not quite sure what you mean on the first point, but I think that's probably an engine limitation more than anything else.
As far as enhancing the teleport range of the charge powers (Shield Charge, Lightning Rod), you can enhance them with standard Range enhancements.

We will honor the past, and fight to the last, it will be a good way to die...
Now before the flames consume the topic, I do not mean alternate animations.. I mean literal change of animations.
the key item I'm talking about is the requirement of being immobile to use some abilities.. most notable on shield charge, lightning rod.. and other location targeting powers.
I think the reason for this is quite clear.. I may not be a heavy role-player, but I like to do some fancy moves to spice up the monotony of running missions..
this varies from running around with ninja run, flip jumping above a horde of mobs then bolting down from the heavens like a bolt of lightning, as the power would imply. to pulling a hammer down with shield charge from mid super jump...
on that note.. we should be able to modify the teleport range on charges.. even just standard io's...
