Well your only temporarily limited as you will still be able to move your skill points over to other skills like in MO1. At least i havnt heard about any change in this.
Yes, you can delete all of your grind progress to grind up something else, and if you find you don't like that, you're free to delete that progress too and have nothing if you want to go back. Never found that concept appealing. Just felt like wasted time that didn't benefit anyone and wasn't fun for anyone because it was usually just spamming shitty left gloves in a crafting bench or something.
In regards to combat skills, it felt even sillier as you could play with a spear for years, but if you didn't have enough points to learn hammers, you would have to make your character forget which way is the pointy end of a spear to let them learn to wield a club. Can't really tell you why, it couldn't be for "realism" as no warrior would ever learn one weapon only, and as far as balance is concerned, its already a full loot game so if you want to bring and use every weapon under the sun, you ought to be able to do so effectively at your own peril. It's not like you can wield them all simultaneously unless you've figured out how to give your thursar khurite some octopus arms.
People complained when everyone restatted during the flanged mace meta, and everyone was only using clubs but there were mounteds everywhere and everyone was wearing heavy armor, and we literally could not use other weapons due to way skills were set up to only allowed one or two weapons effectively at one time. So yeah, nobody branched out, because the game didn't want you to. You want to help cut down on meta set ups? Don't force people into making all-or-nothing choices that promote a need for min-maxing.
