Hey Riklo

MF's E procs Thunderlord in half a second with no additional autos or abilities. And a giant AOE with a heavy slow is kind of hard to miss, even if they land on the edge of it

yeah but it costs mana, a decent chunk of it too AND it's magic damage that doesn't scale with AD. Sure you can abuse it but a good player will know when to hit mf if she keeps spamming it and depleting her mana
