Draconian character creation power set availability due to balance issues?

I like to tell people why I'm putting them on /ignore. There's only a tiny chance they'll learn from my explanation, but it makes me feel better.

I am putting you on /ignore, quickfire, because you aren't trying in any visible way to convince me of your points. You're a lazy arguer, and I've done the thing where I spend half an hour on a reasoned post to be met with 30 seconds of "Nu-uh! You're not the boss of me!" I've done it more than enough.

Sir, madam, or tentacled creature: I bid you good day.

Draconian? Really? Like this guy:

I think, since none of us are being put to death, that "Draconian" is probably a teensy bit hyperbolic

Yes, that's right. Amongst all these statistics and wild opinions, I noticed nobody was doing the Language Police thing, so I thought I'd better sort that right out.

Another negative to allowing the swapping of powersets (after advancing levels):

Even within a specific AT, the options, powers and the way that these combinations play can be vastly different.
The leveling process gives you (the player) experience (real experience, not game xp) with those specific powers.
Learning the game as a Fire/Fire Blaster is a very different experience than a Fire/Devices Blaster.
It's the same with a /Regeneration Scrapper vs. an /Invulnerability Scrapper, a /Trick Arrows vs. /Cold Controller... And so on and so forth.

Sure, the developers could provide an option that wouldn't take any of that into account and let us swap things around that really have little connection, but it has its own negatives and I don't see many positives to come from it.
Mainly... if you want to have a leveled x/x character... level one. It's sort of the basic premise of providing and playing a video game.
I understand where you're coming from, but it is possible that you are placing too much connection between powersets beneath the AT umbrella.
Each powerset, and then powerset combinations as well, can play very differently.
So, jumping from one to the other is somewhat of an artificial breach in integrity of the game as well as possibly damaging to the player's ability/experience and (overall) enjoyment (as they may continue to try and make the /Regen scrapper perform under a strategy gleamed from leveling an /Invuln scrapper, for example).

Not that I think this is a huge problem, nor will it affect the cost of tea in China, but... within the scope of a video game design, I can see it as a mistake to allow such conversions.

I think archetypes add a lot to the game besides the obvious balancing that they provide (just look at the rubbish base numbers corruptors get versus the brilliant values for modern dominators - yet both are just as fun and effective in actual play) because the variation in base numbers and inherents can add diversity that you don't get from power picks alone. Scrappers, Brutes, and Stalkers all choose from the same types of primary/secondary combination, yet they provide substantially different gaming experiences because the sets can be adjusted by archetype, interpreted in the light of base modifiers and attributes, and influenced by inherents. I like archetypes because they add depth beyond which sets you can pick from.
