Don't think anyone has said to start over. I specifically recommended against it. Just seemed like OP was interested in knowing how to optimize, and us people with too much spare time stepped in.
There is no disagreement that this 1) makes you weaker until then and 2) makes you level slower. And in fact, if you intend to use magic offensively (like with Petrify) it's probably a terrible idea to wait until 21, because you'd have 1 skill and be unable to gain more while you can't land spells for shit. Not sure how far you can get with the Lore alone - I don't play nukers.
My journey to 21 is rockier than yours, but my level 21 fatebinder will be stronger than yours.
I feel like I'm repeating myself here. Yes, using magic makes you stronger, but the strongest character is one that uses magic without any skill in it if they're only using it defensively (like with Mirror Image), because the skill experience helps so little apart from leveling you up. The gripe is really with the experience system. That's why we're saying things like avoid magic until level 21 if you want to optimize (and if you want it, you can get 21 with a party, just keep leashing mobs).But mirror image or extra petrify in combat might really help me when i need and wouldn't eat that much of comat time, so i duno, i really doubt extra few bow skills with "optimizing" would give me more that extra control or mirror image.
