No. That would be silly. Fishing does not *directly* relate to how much damage you can dish out or withstand (the fish is tradeable). Nor does Smithing, Cooking, or Agility (although you'd have a slightly better case with agility). Attack, Strength, Defense, Magic, Ranged, Hitpoints, Prayer, and Summoning are all directly related to combat, while Herblore has not been until now (tradeable potions), and the level where it does (untradeable potions) is so ridiculously high that it was stupid of Jagex to ever make them untradeable in my opinion. I do seriously think that they should start adding combat levels once you get Herblore to 84 or above now. And at a pretty insane rate too since it adds like 13 to the max hit of magic. EDIT: But at the same time they should be allowed in PvP. I forgot to mention that.
