what if tear rewarded you for interaction?

part of why tear and its items, manamune especially, are so rare is because it takes so long to stack them up. so what if, instead of giving it just a raw buff to its stacking, you got more if your spells (or autos in manamune's case) are used to hit champions (allies included if it can target them)?

This would be a sizable buff to people who already enjoy the item for sure, but less spammy champions being able to make up for it by hitting enemy champions (and thus scaling faster) might then find the item more appealing

of course manamune will probably need to be adjusted further but i think this might be a good start to opening these items up for people who want to delay their power-spike a bit for a stronger late game
