After playing Mel and playing against mel
I see a lot of posts calling for her nerfs. However, most of what I've seen is pretty over the top. Her range shouldn't get nerfed, any time someone gets close to me it's scary. Yes obviously the root is nice, but it's still difficult to ward off engage champs if you get an inch too close. Nerfing her range would make her kinda useless.
Her ult does do quite a big of damage. If this is nerfed, or rather, if they increase the amount of stacks needed, you'd need quite a bit of sustained/prolonged damage for it to be useful.
Now what I do say needs to be nerfed, is the fact that her abilities appear to be proc'ing her execute. I 100% believe only an auto should proc this. That way, she won't have that insane xerath range passive burst, but she'll still have good poke while needing to commit to the 550 range to proc passive.
She's really fun to play, while she definitely needs a tweak, I just hope they don't ruin her based on some of this day 1 rage.
