So allow me to broaden my perspective for you.
It's a game, filled with magic, dragons, magical surgery (Dawnguard), gods and ungods/demons/whatever, yet the ability to forget and learn a new is far-fetched?
LOL
Yes, because inside of that gaming world you are choosing to become a person where magic, dragons, etc, are reality. However, instantly unlearning a skill and then applying it somewhere else is not a welcomed "feature" for many who role play inside whatever alternate reality has been created for them.
By the by, I wonder how many of these people that say we shouldn't have the ability to respec also play on PC. Because, like, the irony.....I can almost taste it in my mouth.
I play on the PC and I don't want the ability to change my mind on perks. Yes, I realize you will say, "you already can via the console". Well, I never thought of it, but I still have no interest in it. The console, as far as I am concerned, is there to help you out of bugs and for testing mods, etc. I don't use it to 'cheat'. It's not like changing perk selection is a feature on the PC version, there is no menu, there are no instructions, there is just a way (i'm taking everyones word on this) to do it using the console.
I doubt very seriously that the people who play on PC and are against this feature are using the console to change their perks. I would imagine they are fundamentally against the feature. If they are changing perks and then saying they don't want consoles to have the option, then they are hypocritical turd muffins.
