Destruction is NOT on par with Archery, One-Handed, or Two-Handed.
Destruction/Enchanting both at 100 does less damage than an unimproved melee weapon. I've played pretty much every archetype and every build possible and I can confirm this to be true on Master difficulty. Hell, a bow with NO SMITHING/ALCHEMY/ENCHANTING WHATSOEVER will still do more damage than Destruction spell that cost 0 magicka. Those of you that are saying they're on par, what game are you playing?
Care to come up with some numbers?
Incinerate is 90 damage per shot 200 dual cast.
Fireball is 60 damage per shot AoE damage. 132 dual cast. This has longer effective range than an arrow.
When I play an archer, I'm usually happy with 100 damage which goes up to 300 with sneak damage, although I can boost it up to 300-400 with smithing and enchanting.
When I play a sword and board character, I usually go with 50 damage, although I can boost it up to 200-300 with smithing and enchanting.
Style I use for playing a destruction mage is somewhere in between a sneak archer and a sword and board. More forward and less sneaking than an archer, but more distance and more planning than a sword and board character.
I find all 3 styles play fun, although lately I have been on a destruction kick. Before I started playing with destruction, I was concerned that I might not have enough magicka or enough damage if I played without doing enchanting, but it turned out that destruction was perfectly fine without any crafting.
