RDM thoughts and tuning needed

If you're going to look at it that way (and I recommend we do), you also need to account for the mana that would have been generated by the spells you're not casting during the combo. This puts the effective cost of a full melee combo at about 163 mana, as the melee combo expends 160 and generates 35 in the time that you could have generated 38 mana by casting spells.

The problem with looking at the generation is that if you look at the generation in the melee combo, it's all hypothetical mana because you will overcap in that case. Mana wasted on overcapping has a potency of 0. Additionally, the reason we consider mana that could have been generated in the time spent on a weaponskill is because that mana could have been built toward a melee combo, and you can't build very far at all toward another melee combo in place of doing the melee combo.
