I highly disagree for 1 reason, there is no good character. Combat is a big secondary aspect in Fallout, even with the perfect fighter there is always a different combat approuce or some quest you cannot do since you lack the intelligence and the abilitys to complete them.
Did you even read the character templates in those guides? Some of the most balanced ones like team gunfighter or solo sniper both emphasize having good intelligence, which means they have plenty of ways to solve quests AND still have the option for brute force if need be.
The guide really fails for 1 reason, it anolyse if really complete but flawed. Doctor? Combined with Healer perk you won't need stimpacks betwhen the fights. And if you really get crippled then Doctor is also a big skill.
Doctor is a poor skill overall (for FO1 I really wouldn't bother with it at all, but in FO2 it has some quest-related benefits), and Healer perk is one of the worst in the game.
Each level will add 2-5 (Fallout) or 4-10 (Fallout 2) more hit points healed when using the First Aid or Doctor skills. No point taking it at all, since after combat you can heal up by sleeping (time is never really an issue, not even in Fallout 1 when you still have the water chip time limit), and after the beginning stimpaks are more than plentiful in both games.
In F2 Outdoorsman was essensial compared to F1, and the "run to the hub" required you to have those caps for the books. The caps could be gotten by a really combat centric character, which again is forcing you onto 1 build. The fighter.
High AP does not help a [censored] in random encounters in F2 since you would in most cases by peppered to death before round 2 has happend, even before that if you was only a little unlucky.
You could even anolyse it further down to reading the AP requirements for the weapons and precalculate out the needed agi for maximal effect, or go just pick the premade combat character instead.
And quite a bit i read of that guide was not correct, simply because of the way it goes.
What's your reasoning of outdoorsman being essential in FO2? And of course high AP helps avoiding death by bullet overdose - the more you can move in one round, all the more sooner you reach the map edge grid and are free to leave the area if you want to avoid combat. In both games, all the premade characters are flawed in some way (that is, by modifying them they could all be improved to do what they're meant to do).
Would also be great if you can point out some of those incorrect bits of info in the guide.
