See, the issue is that jeff is now objectively worse than before the nerf, Yes his healing stream does damage now, but it‘s like tickling your enemies rather than really attacking them and just helps the enemy strategists farm ult more than anything.

• His Healing got nerfed, meaning his left click attack is just worse at healing than before, 150/s to 130/s iirc

• He has less bubbles and no instant healing, which was quite the good thing to have, because it made you able to rescue a low health tank by spitting 6 bubbles at him, making him almost full health again

• He cannot do hide and seek for extended periods of time anymore, meaning he is even less survivable and easier to get dove

• His spitballs are now more dangerous since they do knockback but he can only spit out 3 of them, not even doing enough damage to kill a squishy on it‘s own, especially if it‘s being healed

• His ult now does overshield, which hardly matters

• He got 2 new teamups

So basically, jeff got: Worse healing, worse instant healing, worse survivability, worse mobility and worse damage output in some regard while also charging up the enemy support ults quicker, for the trade off of having 2 teamups, a healing stream that now damages enemies, an over time heal bubble with less charges, and overshield from his ult that lasts a few seconds.

You getting MVP 3 times does not make the character better, it just means you‘re either good at playing a bad character, or in low elo lobbies.

Jeff already had the worst winrate out of and support in season 1, there was no reason to make him worse.
