Certainly at middling or higher levels giving up 3, 4, or even 5 arrows is not usually a good trade for 1 arrow that might force a Concentration check the Wizard is likely to succeed at.
Readying works reasonably well at low levels, or if there are lots of mooks around.
I agree in part. At levels, say, 10+, if you want to stop a spellcaster dead in his tracks, you can simply "ready" a "silence'" spell (to be cast when the enemy spellcaster starts to cast). (or read it from a scroll, or zap a wand of it). This stops nearly all spellcasting without a roll/save/SR/anything. Period. Unless the enemy spellcaster knows what's coming up, or is casting a silenced spell just coincidentally, it's a wonderful way to stop even a level 20 wizard. At least for one round. Next round, they might very well cast a silenced whatever (if they have one). Still, you have gained a round.
*thinking* a cohort with a wand of silence whose job is to silence (obvious) spellcasting opponents would be a nice addition to any party. *thinking*
"Readying" is also useful at high levels when you can't DO a full attack. If you must move to get the enemy into range, or just to see them, you can only shoot once anyway. Might as well make it a readied action. You aren't missing out on anything, and you might, just might, stop a spell in addition to doing damage.
The only other exception I can think of is the "huge damage 1 shot" archer. Using appropriate bane arrows and magical bows, smite capabiliteis if they work at range for the class in question, other one-shot buffs, etc. if you can get a single arrow to do 30+ damage, that will beat the concentration check of most high level wizards. That's probably worth it (4 attacks , 3 hitting, each doing 15-20, or 1 very accurate arrow doing 30+ and interrupting spells?). Most people would probably still do a full attack. But it makes sense if the archer in question can pile a bunch of bonuses/special abilities onto 1 shot, which he isn't able to do with 4 shots.
That's probably it. Pretty rare at high levels.
Poison is a good idea, however.
