EB and all
I guess we simply don't play the same game.
We do have lots of encounters that take place in plains, humongous caverns or rooms.
I've never saw a fighter/thief/sorcerer/OotBI/AA (add any PrC you want). As mentionned in another archery thread, we don't like stacking PrCs. Never done it but some of us may be tempted to take a second one eventually.
Power attack is used against everything that moves, not just objects or DR creatures. Not always mind you (some critters are just too hard to hit to take penalties on your attack bonus) but more often than not.
Archers were often either chased until they got caught and had to fight with melee weapons or were victims of magical attacks. But both archers and spellcasters usually have to fight hand-to-hand (or stop fighting and run) eventually since the meleers will try to reach them as soon as they can.
Don't get me wrong, they are powerul and can dish out very impressive damage. But they are (in my experience, YMMV) easier to take out than meleers (less AC/defensive capabilities, less hps and that is a disadvantage that will not show in your mathematical analysis... In fact, while analysis can be useful, I usually don't rely on them too much to establish balance issues since many factors are forgotten. Not intentionally but there are too many to consider them all.
If your question is: Do archers deal more damage tham meleer, the answer is yes, as established by the different analysis that were posted. I didn't see the point in discussing this further after 3 pages worth of posts already on the subject.
My point was rather that if you take the meleer and the archer both through 10 fights, held in 10 different settings and situations, they'll both have their moments and they'll both be sometimes powerless. Will the archer outshine the meleer at the end, providing both are still standing? That is what remains to be established, in my opinion.
If, as I think, they end up being as useful and interesting to play, where's the balance problem? If no balance problems, why are we even arguing about this?
