Aww.... I suck.... (Hero Recognition)

How do I get WC3 to accept a new unit as a hero (Ex: Sylvanas Windrunner, & a modified Blood Mage for 'High Elves')

what exactly you mean?

base the hero off another hero i.e., paladin. then just change the model used to bloodmage or something.

If your talking imported unit, you have to import them first then modify them after with the new units skins.

When you post please take care in typing it so everyone can understand what your talking about.
