Very interesting topic...
We shouldn't forget though that magic does not exclusively takes form as spells and supernatural abilities in the Forgotten Realms. Expecially in our server I'd say that the biggest amount of magic power is carried in form of magical equipment, regardless the characther is a caster or not.
It's very easy to find enchanted armors, weapons, clothes, potions and rings and they have enough power to transform a character, deeply. This is still magic! It's still connected to the Weave and if you think it's not relevant try to put any character inside an anti-magic field:
Would they be the same heroes? What would happen to their AC, for example? What about their attack bonus or their spell DC? What about the magical damage from the weapons? Would you be able to face the same opponents with the same amount of effort? It's a retoric question, of course you wouldn't.
I've always had the impression that in the Forgotten Realms enchanted items should be very rare: if I have to mention one of my favorite, Drizz't do Urden, he found one of his scimitars in the den of a white dragon, after a deadly fight. Also, he took his bracers of dexterity (later put at his ankles to have a quicker footwork) from one of the best Weapon Masters in Menzoberranzan, after defeating him in a duel. This warrior was from a noble family and if I'm not mistaken they were a very important heritage.
So you can't really find them in the shop around the corner, can you? ^_^
What I'm trying to say is that if a cleric/wizard/magician in your group grants you the power of a magic armor, or a +4 enchantment for your blade or a bull's strength spell, it's not perceived as great as it should be. Someone as arleady pointed that out: in the server magic is everywhere and it's very accessible so we got used to it. I don't know how casters feel about this (I've never played one) but that's just my point of view that I wanted to share
