1. you no longer need permanent investments in the crafting skills you can just respect into them when needed, this allows a good 12-15 new perks freed up
2.you can style your bulit per questline , eg you can invest in lock picking sneak and pick pocketing for theif quests,
3.you can get rid of ill spend perks and fix up bulids
4. you can change bulids whenever you like and this means you only really need 1 lvl 81
5. actully makes it quicker to lvl because you can just max out the perk tree your levling then reset it
I understand your point, however Its not about it being good, bad, unfair or w/e you want to call it.. Console players now finally have the freedom to change their face and hair (DG) and respec if they want.. like the PC players out there.
I personally enjoy making a build and then levelling with it, this option is not for me, but having the freedom.. is something us console players have hoped for a looong time.
