You think you should have the immense utility that magic brings while also having all the upfront damage of the single specialized weapon?
Does that bow also summon companions, turn you invisible, heal you, let you breathe under water, fear people, frenzy enemies, on and on?
No, but Archery is one tree, like Destruction is one tree.
Destruction should, when at 100 and fully perked, be able to deal as much damage as rank 100 and all perks in Archery.
If we remove enchants and potions from the equation, is this the case?
This is not about 'Magic Users', this is about wasting perks on a tree that becomes ineffective in the later game, thus negating all of those points you dropped into it you could have put into a different tree.
I agree with the idea that there should be higher level versions of novice/apprentice spells, so that damage continues to scale up to the damage cap for other trees.
