First off, the EK is not the default mode the fighter runs in. Of the three fighter archetypes, it's the most radical departure from the stock model. If I want my fighter to cast spells, I have to opt in to it. In 4e, before 2010, I was forced to use the same mechanical system as the wizard's spells (adeu) even if I didn't want "spells".
Of course, you put "spells" in quotes, because you know they weren't spells. 'Casting spells' isn't the issue. As you go on to spell out:
The power system gave the aesthetic of every class looking the same. Each class was given page after page of dry, technical blocks with maybe one page of italics text to explain what you are supposed to be doing in game. On paper, each class was a barren landscape of jargon, prefaced with about half a page of fluff.
Almost as if I had asked for another example of this same sort of inconsistency, you provide one. The claim is that using a similar mechanical format for different things makes them aesthetically 'the same.'
Now, we can find multiple examples of that happening in each modern edition. Skills, for instance, all use the same format and the same resolution, yet they're not objected to as 'samey.' The wizard, cleric, and druid use the same format, same casting system, and even actually share some of the same spells amongst themselves, but no objection.
Clearly the objection is not to mechanics using a consistent format, but to what they mean in the broader context of the whole game:
I'll take evocative chaos over bland balance.
...
So maybe presentation does matter. There is a word for classes that are perfectly balanced because the all use one chassis to build them: samey.
So, the objection, is, at bottom, to balance, itself. Once viewed in that light, the inconsistency is resolved.
I don't think it really matters either way since my point was that you stating martial powers ruined the game for me was false...
You reject limited-use mechanics in one system, but not in another. That's the inconsistency, you also said their 'dissonance' contributed to your rejection of 4e, which is tangental, yes, and not that interesting. You go on to provide more and more detail to explain how one instance is different, yet each new objection you uncover in one turns out to be present in the other, as well. The inconsistency remains.
It could be resolved, but, not, I suspect, without looking at the bigger picture rather than deeper detail.
*Sigh* are you really interested in knowing why or are we just going to keep going until the point where the abstraction doesn't line up and you can say gotcha!!
If so let me know now and we can end this conversation...
I'm not sure what you're getting at with the not-lining-up 'gotchya' - AFAICT, that's where we started - but the rest of your response seems to wander from the topic at hand, and you do keep presenting two different rationales for things that are essentially the same, with the only difference being the context in which they occur.
While it would be nice to take a step back and see if we could find out what about that context is problematic in one case, and excuses any issues in the other, your unwillingness to do so merely leaves an example of the kind of inconsistencies we were talking about, sadly unresolved.
