No. You can use charms and equipment bonuses to augment any stats you may have neglected.
What level are you? If you just got the battle tower you may be able to change how you distribute stat points as you level, but late in the game it would be harder to make a huge change in character build. You may still be able to make an effective build, though, even without an optimal stat distribution.
Playing an archer in DKS I stopped assigning stat points after level 15, and have almost 100 unused points at the end of the D2:ED section of the game. I forget when I stopped assigning stat points in D2:ED, but at the end of the game (level 36) my duel wielding strength based warrior had 39 unused stat points.
