When it comes down to it, the whole playstyle thing is dumbing down the character creation to make it more accessible to novice players.
I think that anyone is going to admit that new player shouldn't be starting off placing an Arachnos Soldier, Arachnos Widow, or Kheldian.
I would even say that a new player shouldn't be playing a mastermind.
It would be good to have a gate in character creation that allows you to pick "new player", "guided" or "experienced player".
The "new player" path would ask you from the beginning if you want to create a hero or villain (no Preatorian option). From there you would be gated into a revised playstyle listing with the archetype selections being only the original ones from CoH and CoV (no Arachnos Soldier, Arachnos Widow, or Kheldian). After power selection, it is the same (except that you have already picked if you are a hero or villain.) By default, you go to the tutorial as you are a new player. I would go as far as to automatically "gift" them some things from the P2W vendor (the enhances at least for sure).
The "guided" path would put you into what the current character creation system looks like.
The "experienced player" path takes you to as list of all the Archetypes. After Archetype selection, it functions the same as the current character creator.
Setting it up this way allows ease of use.
Helps new players easily learn the fundamentals of the game before getting into situations that are even more complicated.
Helps those that aren't sure that they completely understand the Archetypes.
Gives ease of access to archetypes to those that already understand what the archetypes are.
