I don't really think it impacts progession the way you're thinking. If I want the 10 perks(for instance) for Marksman. In order to get the 10th perk, I'm going to have to take perks 1 thru 7,8 or 9, before I'd qualify for 10. The previous perks, along with your skill, would dictate what perk you may take next. So it's not like you're getting over on any of the perks, you're simply biding your time until you figure out, thru playing the game and being your character, which direction you want to go in.
I'll bring up another scenario, what if you hit level 50, but don't have one of your skills maxed out for a high level perk you wanted? It would be a shame to not have a solution to fix that challenge.
But this happens naturally in the first place, tossing out 10 perks at once after saving them up would be like falling asleep being a complete [censored] and waking up being a master at somethign you have little experience with.
If you were able to save them and continue playing then you could raise all stats and just dump them in whatever, which goes completely against the perks/leveling being dictated by the things you do the most...not having to spend them would also basically destroy the point of having the skill caps in the first place.
And im sure they have a system in place so that if ur barely away from the cap(if there is one in the sense your thinking of) to not prevent you from taking what you want If youre going for the high end sword perks youll be using your sword the most anyways so it shouldnt be a problem, the point is your playing the way you like the whole way and that makes you who you are. Im under the impression that just the fact that youre using your sword more often than casting magic opens up the one handed perk tree which then zeroes in on the sword specific perks like was stated in the interview.
You people seem to just want a free max lvl with a fresh perk set that you can throw wherever, while at the same time NOT wanting to play your character to reach that set. People dont practice swordsmanship their whole life and then in an instant decide theyre actually super good at archery and learn a bunch of fancy new tricks.
Like todd said, you see a perk you like in the sword tree...you start using the sword more.
