I think it should just be siphoned both by damage received and 'dealt'. Perhaps make it champions only so you don't regain insane mana off of the creep wave or jungle, but adding in the capacity to get mana by 'winning' a trade as well as losing a trade I think would secure it's place in the mana item roster.

The problem with this is that you aren't getting manna off winning a trade if its both. you are getting mana back for just trading, since you get it for both.
Not to say I am against the idea. Just disagree with your reasoning here.
RocketRelm1 votesWell, my point was more addressing the fact that the current version of catalyst doesn't let you get mana back from trading, while my suggestion gives you agency in the way you regain your mana. Noted though, and thanks. I'll make a quick edit.
ChaddyFantome1 votesOf course it does. A trade involves a back and forth. What the current one doesn't do is let you get mana back for simply harassing.
Which may or may not have been the intention since it'd be pretty obnoxious to just get infinite mana back by throwing Q's as 
or 
with impunity.
While the question of agency is a good one, I think maybe some more restrictions would need to be made or something.
RocketRelm1 votesYeah, there would almost certainly need to be number tweaks. Hell, maybe even a separate item, one for the taking damage version, one for the giving damage version (build paths would be an issue, but Jungling items have worked with worse). That way there's an item for the Swain/Chogaths that cycle their HP a lot, or whoever would really thrive with the current catalyst, and an item that rewards actively putting damage onto enemy champions.
