And note that this isn't necessarily a matter of 'easy mode' or simplification. It is more a matter of just streamlining the game experience. I can be the greatest living charops expert and there's no reason why I shouldn't just play a Slayer if that's the kind of character I want and it does what I want.
Last month there was a large playtest article in Dragon that provided multi-class and hybrid options for many of the classes from HotFK and HoS.
Huh, requires offhand to not hold a weapon or a shield. Nothing about an implement.
Go bladesingers with a spear and orb! Chaaaaaaaarge~

So you can be a Spearsinger (there's one handed spears right?) or an Axesinger, or a Whipsinger, or one-handed melee singer of choice. And that's a single feat; though someone will arguably bring it up as a feat tax issue; but blades are some of the best weapons around anyway...
DIS would only apply to your dailies, though. Bladespells don't use damage rolls, or even have the Implement keyword, I think.Yup, the off hand doesn't have to be empty, it just can't hold a weapon or a shield. You could use any implement in it. DIS might be a cool option.
Also, everyone has forgotten about the existence of Versatile Expertise? Yeah, it is one of the OLD expertise feats, but it would still be highly relevant, especially if you were to say want to play yourself say a dwarven axesinger (it is the guys he hits that do the singing).
