Dang, what a long comment (lol) I'll try to explain a little better...

Only a DOUBLE type would take the X3 damage, the single types would still take the X2 damage from their weakness. In other words, off your example, Fire would be weak to Water only, Light would be weak to Dark only, but a Fire/Light unit would take X2 damage from either Water or Dark, or the X3 damage from a Water/Dark unit. Better? Just think of it like Pokemon, Dude.

But I do like the idea you mention in the second paragraph. BTW, I still don't really know how much damage a Unit takes from it's weakness and all, so I guessed the damage XD. Also, I keep seeing X3 as a face, so lol. Thanks for the lols and the words!
