Yeah, I think we're going to go with that. Which means that the spellshape attack feature will change to:
Spellshape Channeling (Sp): As a spellshape champion, you have the ability to shape magical energy into attacks: lashing zephyr, sunfire, rockslam, caustic spray, withering hand, moonflare, thornspike, frostray, surging jet, fireblast, galvanic arc, and kinetic blast. However, unlike other spellshapers, you cannot simply blast foes from afar. Instead, you channel this energy into your weapon and shape your formulae from the front lines.
During your turn, you can channel one of your spellshape attacks into a melee weapon that you hold as a free action that does not provoke attacks of opportunity. Until the end of your turn, your melee attacks deal their damage as the damage type of the spellshape attack of your choice. This damage is equal to your normal melee damage, and you still gain all the normal benefits from a high Strength score, feats, and other effects that increase your melee damage. For example, an attack with a longsword that normally deals 1d8+4 points of slashing damage would instead deal 1d8+4 points of cold damage if you were channeling frostray through your weapon. If the spellshape attack you are channeling normally allows spell resistance, you much succeed on a shaper level check in order to damage a creature with spell resistance with your attack. You otherwise attack with your weapon as normal.
When channeling a spellshape attack through a melee weapon, you may treat attacks with that melee weapon as the spellshape attack for the purpose of shaping major and minor formulae. Shaping a formula in this way does not provoke attacks of opportunity.
This means that the existing instances of spellshape channeling will have to be changed and replaced, along with the lifted Warblade abilities. I'll get on that later tonight.
