Hmmm...sometime I must start a thread on whether anyone's actually DMing a 3.5 rules game at present. I didn't want to waste the group's time with my background before asking my question but, in short: I've been DMing D&D on and off since 1975, which almost by definition makes me "old school", to wit:
I have zero problem with the "PCs can't do it, but the baddies can" (see old-school, above), and:
Perhaps, but the advantage of being the only person who's willing to DM a 3.5 game does come in handy. My gaming group is so desperate to play anything that's not 5E (which we loathe) that I could probably make them wear tinfoil hats and chant "the DM is great!" every hour and they'd still want to play! However, where I live may be unusual in that respect...and I'm not that big of a d*ck.
Anyway, thanks for all the advice, especially about the non-T1 classes using wands & scrolls more. Again, that wasn't my experience when I ran my last 3.5 game back in 2005 - 2010. So I'm leaning towards letting the swift casting as a Move action stand.
