Shift AP to AD on Rageblade?

I was wondering if a slight change to Rageblade could help make it more viable. The problem with Rageblade is that it has wasted stats that most champs it could be used on dont need. I'm talking about the 50AP. This item seems to only be really viable on Kog'Maw who stacks a ton of oh-hits, has crazy attack speed, and has multiple AP ratios. Since Rageblade is also a very expensive item (sitting at 3600g), it makes it very unappealing to most champions that could make use of its passive

My proposed change would be this:

CURRENT :

• 35AD

• 50AP

NEW :

• 50AD

• 30AP

You will notice that 5AP is actually lost (+15AD, -20AP) and that has to do with flat AD costing more than flat AP. That number could be lowered to 25AP if necessary. The recipe would have to be changed to avoid losing 10 AP from the Blasting Wand. That would easily be solved by replacing it with an Amplifying Tomb, but increasing the combine cost.

Overall I think this would make the item more appealing to a wider variety of champions. As it sits now its a very expensive niche item that could be so much more with very little change
