It would be like if Minsc in BG2 had 14 Str but high Int and you were supposed to dual-class him to mage. WTF.
It is a class choice that makes Minsc suck - Ranger is nothing more than a poor man's Fighter without grand-mastery under AD&D 2.5 and his weapon choice (2-handed sword) nullifies only useful class feature he has, free dual-wielding.
Imho, BG 2 is extremely bad example when trying to prove ineptness of P:K companions. Almost everyone in BG has some critical flaw, sometimes several. STR, for example, on some (multi-) fighters:
- Jaheira, 15
- Keldorn, 17 (horrible dex)
- Mazzy, 15
- Valigar, 17 (ranger too, can't wear heavy armor)
And 17 in older system is nowhere close to Pathfinder's 17, it translates into pathetic +1 Attack & Damage that much closer to 12-14 in 3.5 era.
And among those with 18 STR:
- Anomen (horrible dex, no longer levels as fighter)
- Korgan (best fighter in the game, still bad dex and batshit evil crazy)
- Minsk (bad dex, shitty class)
