High Magic Double plus good...
In a really high magic game no one can crank out more damage than an archer consistantly. One simple reason (if it didn't change in 3.5), enchantment from the bow and the arrows stack... +5, speed, shock bow with a set of 5 x (+5, returning, energy etc.) for a combined ungodly +10 at least two shots plus whatever you get by class or rapid/multishot, and extra energy damage for seasoning purposes. You can basically hit whatever you want a lot of times, and play fun tricks like "I want to shoot the wizard through the scroll he is reading with a flaming arrow." Under our house rules, it was about +8 for a head sized called shot target, so you would still get a plus two, (or zero if the DM is being tough on you). And whether or not you hit him, you can always make the arguement that the enchantment on his clothing doesn't really apply to the scroll he is holding in front of his body, thus he would only get his dex bonus +10. Concentration check doesn't mean much when there is nothing to read.
You can also have fun with a high initiative by holding your shot for the oppontent magic users to start there thing and preemptively pop them one; it adds to the concentration check (damage and flaming apparel), and if they make the first check, pop them again. Continue (shoot hold) till either spell or wizard is wrecked. For that matter, there really is no reason for an archer not in the thick of things to not hold there shot for the end of the round. Survey the battle field. See who needs help and who doesn't.
There is one flaw in this plan. By book rules, arrows break every time they hit and 50% of the time when they miss. But really come on, if you are putting that much magic (or any at all really) into an arrow, I think you should also pay the wizard to research an enchantment that would harden an arrow on par with any other weapon. Especially if it is returning, I don't think there would be much arguement about negating that breakage rule.
If you could not tell, they are my favorite. Always seem to gravitate back to them.
