That's cool, you have every right to want to do what you want in the game. To me, it's one of those things that sounds great in principle, but I would never use. I mean, getting to 62 required me to do basically everything. I'm not going to grind out repetitive radiant quests after that.
The only skill I grind is blocking, which I admit is extremely tedious. The rest of it comes from just playing the game and taking a long time to get anywhere. After becoming Thane of Whiterun, it took me another 8 months in game to get a major quest added to my journal.
And for the record, even if I could max out the perks, I still would end up not using two hand and block and most other skills outside my basic build, but for my RPing purposes, absorbing dragon souls is making my character more like a dragon, which in turn enhances my mortal body, which is illustrated in the perks I select.
If I could just select the perks I wanted when I was at the appropriate level in that skill, I'd be okay with that. But since we have this system of Perk A unlocks Perk B which unlocks Perks C and D, I'd like the option to continue expanding my powers after I hit the level cap.
