Sword and shield user with "R" to switch between fighter(sword) scaling with AD, and support(shield) scaling with armor/MR and AP. Thinking like a paladin where he use the power of light as rescouce to deal damage but in shield for has mana but light will give increased affects on skills like using a heal spell will also replenish some mana too
First of you want both forms to scale simliarly to a certain degree, unless you want to have one form that is inherently worse than the other. Changing resources sounds weird, either have one form generate the ressource and the other form spend it, or have mana on both. Overall sounds doable and would make for an interesting champion.
his fighter stance could be an initiator and support a peeler and the light resource could be special like certain abilities would generate it and yeah about even maybe more towards the support stance though
