why u so afraid? she not even get a a buff quite long time. i asume u not read all of it. even a bruno a cheap mm get huge buff u think this a fair game? u think moonton is fair on everything?
You are buffing her because of 1 mm. There are a lot of mm that she performs in certain team comp. 4.5 seconds is overkill because it is the equalivalent of 2 times more than minos knockup duration. She is a hero with low dmg but she makes it up for her superb teamfight capabilities. However, with that said; she needs a buff.
miya revamp is not the best. 3 other mm. What else. She is meant to low dmg in 1v1 for mm. However, she has the ability to crit and 1000 to everyone close by. Buffing her hard like those mm; would mean she could get easy savage every game if your team consisted of 4 tanks protecting her.
What I am saying is that she needs a buff or revamp. However, your revamps are overkilling her or making her to op. I agree with some of ideas but the buffes or suggestion you made should be toned down. For example the 4.5 second stun is insane. I will make it 2 second stun at most instead since 2 seconds stun is the most any tanks will stun anyone.
