This is only easier if the player is already familiar with all the PrC's being used in the campaign and the requirements/prerequisites for every one that he/she might be interested in playing.
I think the fundamental thing behind here:
People assume that feats, skills, powers, spells, prestige classes, paragon paths, epic destinies, racial substitution levels and so on are important and they want to optimize them. You get better for picking the right feats, spells, skills or powers.
But you could just pick the first thing that you find. Your character is still playable, he doesn't become invalid or anything. You just don't get that extra inch or mile of performance out of it.
But so what? When you didn't have any of these options, you didn't get any extra performance either. If you could live with it then, you can live with it now.
The thing Storm Raven seems to be missing, though:
Players have different preferences. Some like this optimizing and do not miss the "easier" times. But other players want that easier times. Sit them at the same game table, and you create conflicts, because the optimizer will have a far easier time to get the spotlight then the suboptimal characters.
So to fulfill what you miss from old games and still have a satisfying experience, you also need players that miss the same. And you might have had them then, but you might not have them now. And you might not get the old ones back and might like the current ones too much to just give them up.
