What exactly does "not seamlessly" mean

[Dice4Hire]

I offer you an emphatic MEH.

Boohoo, you can't take Cleaving Stance so I guess you'll have to suffer with... Cleave. Which works out to have the same effect in over 95% of cases. Same with Reaping Stance and Reaping Strike, etc. etc. etc..

Go past the point of a post often?

Th point I was making, as others have posted in this thread, is that, up to essentials, a class could take all the powers in the class, though, certainly, some of them were sub-optimal, and in the case of the Tempest fighteresque powers, might well mean changing weapons mid-fight.

Battlerager? Not a big problem, take endurance, and you can get something out of those invigorating powers.

It is annoying when WOTC says this is 4E, but makes it very hard to use those options to their fullest. Which, of course, is what Essentials is not really 4E, it is 4.5E

Apologies if I interrupted your hyperbole

A Knight though cannot pick fighter powers.

No, knights can totally take fighter powers. It's just that the only powers they get are utilities (which can come from the fighter list). If you had some other way of getting class powers (human bonus at will and paragon path bonus encounter, for instance) you could take fighter powers.
