I feel like Lich Bane could use the magic damage convert Runeglaive used to have.

And no, it won't bring back Runeglaive Ezreal again.

Why you may ask?

1. He'll still have a pitiful wave-clear.
2. It won't help his mana problems at all.
3. His Mystic Shot won't proc Luden's Echo again.
4. It is more expensive than Runeglaive AND you'll still have to spend money for your mana regen item.

I feel like it would be a QoL buff for the item, as it makes Lich Bane a better synergy with magic penetration. Plus, usually, Lich Bane users have relatively low Base AD anyway, so it wouldn't do that much late game, except for a 100 magic damage instead of 100 physical damage.

Thoughts?
