I just said you 'should' be able to. Jeesus. What the hell is wrong with you?? Go pick a fight somewhere else.
There is a way to do it anyway. Don't do weapon specialities. Take the generic poison damage. Use spells or traps or whatever until you find a weapon that makes you go 'Sweet!' and then specialise. Not that difficult to figure out.
Your example still doesn't hold water. I was just using weapons as an example. If you get other skills you're still using or wasting those same skill points that could've gone into others. I guess the point is, as people have stated, you're forced into far too narrow of choices to be effective. The problem is, you will probably say 'Sweet!' more than 4-5 times throughout the game as you find new and better weapons. These weapons will not always be the same exact type that you have already invested skill points into.
