Nah, not really. The feat cost for multiclassing is very heavy, close to 50% of the feats in heroic, and if going into paragon, the loss of real prestige path abilities is hard also. Add in implement problems and ability score requirements and it is just a pain.
As for hybrid, some classes are not bad, true, but you only pulled out maybe 3 of hundreds of combinations. It is not hard for a few to be good. But when so many are just unworkable, it is a problem and a poor system.
Go ahead and rolls the dice for two random classes and hybridize them. Not likely to work well. Take a random class and roll dice to select powers and you are pretty good, not probably not great.
But overall 4E is pretty well balanced, especially if one stays within the class powers and roles.
I imagine that randomly selecting two classes to hybrid works out about as well as randomly assigning your stats for a single classed character.
The feat cost for multiclassing is 1 feat, and that one feat is equal to two feats -you get training in a skill (skill training) plus whatever other benefit comes with MCing in that class. So, you're actually one feat ahead at this point. For a lot of multiclass combos, this is all you need to be good because it opens up options which are otherwise not available to you.
If you want to paragon multiclass, you need to pick up three more feats, so, yes, you end up being down 2 feats overall. Yes, I agree that not all combinations are good. However, some powers become very good in the hands of other classes. Missing out on the paragon path action point feature does somewhat suck, and I would never suggest paragon multiclassing was optimized, but I've found that I don't miss the AP feature as much as I thought I would.
This is very simply revisionist history. The single most unbalanced source for PCs is the PHB1. And right now there is nothing that measures up to a Ranger with pre-errata Blade Cascade or a classic stunlocking Orb Wizard/Bloodmage. A Warlock made using only PHB1 is right at the bottom of the power curve - which is also a function of it coming from the single most unbalanced book. That said, with more feats it's a lot easier to specialise and dump all your resources into the same thing. And Expertise and Themes are examples of creep.
I was assuming errata in my answer. If I don't consider errata, then my answer of no becomes no.
