Strawman; kiting is no exploit, certainly not in a game that's tailored for it like BG. Of course you can stand there and duke it out with a tank who will hit an ogre approx. 1 out of ten 10 times with his longsword (if he has exceptional strength), and do the reload game until your fingers bleed because he will "chunk" you in one or two hits, which means game over (for the protagonist) or no ressurrection (for a companion).
Unfortunately, you've provided absolutely no proof of your claim that the developers "tailored" the game to be one of kiting with bows. It makes absolutely no sense at all that they would, so your point is both irrational and weak.
If you think kiting is the only way to play the game, then you're being ignorant of the options available. If you think it's the only way to be efficient in the game, then you're being ignorant of the options available.
It's common sense that the developers did what they could to adapt the PnP rules of AD&D 2nd Edition given the time and resources available.
I think they did a fine job - even if the game has plenty of weaknesses.
Playing the game exclusively with ranged characters, kiting enemies across the map is clearly not what they intended as THE way to play - as they implemented a lot of classes that can't use bows - and they implemented a lot of NPCs meant to join your party that can't use bows.
Essentially, you discovered that bows are efficient at kiting enemies - and you've stared yourself blind. You've obviously overlooked several powergaming avenues - and it takes but a few minutes of googling to discover other ways to "break" the game.
If that's your thing - so be it. But trying to tell people your way is the only way is not only ignorant - it's selfish and arrogant.
Not a very impressive position - but that's on you.
I've heard that same argument before from people defending i.e. BG; you don't have to kite. It's just that you're shooting yourself in the foot if you don't do it, and that kind of artificial difficulty is for LARPers, not for anyone else. In a game, there's no alternative to gaming the system. Would you call a game a timeless classic even though it's ridiculously easy, because you can play without weapons for increased challenge?
Why don't you give us all some examples of old RPGs that can't be exploited in a similar way.
I'm really curious to hear about some of your favorite games - and please give us some titles of games you consider classic RPGs.
I'm sure I'm not the only one curious to hear about these games that you can't "break".
