Sure, but it's not just about the abilities themselves. It's about the rhythm of the class. AEDU has all classes playing to the same rhythm on different instruments. With more varied resource mechanics, every class marches to the beat of a different drum.
Obviously I'm not going to agree. I mean, sure, there's technically an equal distribution of powers of each type in all classes. OTOH there are pretty large differences in terms of how a given type fits into a class and how it is leveraged.
Fighters, for instance, are foundationally built on exercising their class features, and this ties into their basic and at-will attacks. Those attacks also have a lot of buffs and there's an entire level of complexity involved in how they interact with weapons and a vast array of feats which impact that. So, for a fighter going around with their 'bread and butter' powers is normal. Their daily powers are OFTEN reliable, so that's quite different from, say a wizard as well (I can't think of even one reliable wizard daily).
So, what you will find with the fighter is that the 'beats' are MUCH less concerned with which powers do I have available, and much more concerned with action economy, movement, marking, use of action points, etc. Honestly, you don't even really look to dailies for 'big moves' in fighter land. They can HELP, but what you really look for is some synergistic situation where you can AP, your buddy the warlord can pump you up, etc.
The Wizard by contrast is HEAVILY oriented around daily power. He can do some interesting things with at-will/encounter powers, definitely, but its mostly about when and where the daily will entirely whack the enemy's plans. While there are certainly many synergies and fiddlings with implements and such its much less about that stuff than about "Wall of Ice" is going to hose the bad guys NOW, HERE.
Playing each of these is radically different. Enough that I can remember one day when one player who was running, I think, a warden, had switched to wizard, and all of a sudden she 'got it' and the encounters went from difficult to cheese in one round. She'd just been playing a wizard like a warden, and they are completely different beasts. This is the reality of 4e, each class is really unique.
