Well, I have nothing against a character with 'All the World's a Nail', as if they have even mildly decent Wisdom they can often end up Cutting the Knot. I plan on making a berserker-esque Warblade at some point with high intelligence, yet they still prefer brute force. Well-placed brute force, but brute force nonetheless.
Ability scores are not everything, and they can be interpreted in a lot of ways. Ness has low wisdom, and so she can make poor decisions, gets distracted easily, is playful, etc., but she's not cowed easily, and she's not stupid or completely lacking in insight. It balances out to an 8. Similarly, my duelist character in another thread is/was fairly handsome, but has an 8 in Charisma because of his personality and poor real social skills (beyond 'I have never lost a duel. You will pay me what I wish for my services.'). And so on. I want to make a Rogue with 18 Dexterity at some point who happens to be obese(or at least would be classified as obese), because being large and being agile are usually seen as mutually exclusive(to be honest, I kinda want to make him a Scout or something, maybe a Monk, simply because I can justify the fast movement speed as rolling like Choji does and popping up to stab people).
Woo rambling!
Oh, unrelated but DnD related; I've been wanting to make a 'fix' for the monk, possibly the ninja, samurai, sohei, and so on, with Ki Powers. I was thinking they would work in a similar vein to maneuvers, but more supernatural. Basically, they are to maneuvers what psionics are to magic. Basically.
I also kinda wanted to 'fix' the Fighter and similar classes by introducing Proficiency points. Different classes get different amounts, you put them into various weapon groups and are proficient with them, some weapons cost more than others, and you'd probably gain an amount in a fashion similar to skill points. Could 'buy' certain feats with them, get certain abilities, etc....trouble is balancing it all and it's an entirely new mechanic. My other idea was bonus abilities similar to rogue's, whenever they gain a level without gaining a feat, or every third level, or something.
Finally, I had the idea for including the Parry skill. Not exactly like NWN2's version, of course, but using it in place of things like Combat Expertise, and meaning that two level 20 fighters with nothing but greatswords doesn't just turn into a hacking contest(since they almost literally can't miss). That's always seemed incredibly dumb to me, since getting better at fighting includes the ability to not get hit, not just to hit the other guy.
