1. Interesting, but making it +3% per level, per opponent could quickly spiral into hugely unbalanced territory. Combat abilities go up to 15, so maxed it would be +45% for one enemy, +135% for three enemies. It would also be difficult to manage balance when you could have a bonus of between +0% and +145% depending on your Warfare and the number of enemies around.
2. A long time ago, I suggested that a possible nerf for heavy weapons would be lowered movement, but that suggestion was unpopular because having to use up all your AP to move and being unable to attack much was un-fun.
3. There was a vote on new skill trees, one included the Guardian tree for defense-oriented warriors. It lost both votes.
