Can we re-buff the champs that were nerfed for pro play?
I'm talking about

They were gutted right before Worlds, and I was hoping to see some improvements in patches after Worlds, but so far they've seen nothing.
There was talk about pulling safety/flexibility out of Akali's R (making the first cast targeted) so that she could get buffed in other areas. I'd love to have that see the light of day. Honestly, I think Akali should get balanced around being a skirmisher, not an assassin. Her extreme safety and ability to just stand in the middle of a teamfight dishing out damage with her shroud is more fitting for a skirmisher, but she has the burst of an assassin.
Aatrox was problematic because he did it all. He had sustain, waveclear, mobility, roaming power, hard CC. He's supposed to be a juggernaut, but he can honestly function as a diver for his team. I think they should trim away some of the fat and really drive his identity as a juggernaut home. Juggernauts typically don't have mobility or consistent hard CC, so make his Qs apply a heavy slow instead of a knockup and reduce the movement speed he gets in his ult. In exchange, give him more damage and better sustain. Perhaps increase the damage of his Q edge, or improve the healing he gets from fighting champions. His ult could also incorporate a fear-like effect, slowing enemies who try to move away from him instead of giving him a massive speed boost.
Tahm really needs some love. I think a great place to start would be the readability of his W. When you get eaten, you get no indicator. There's no sound effect, no visuals, nothing. This makes it easy to get out of Tahm's belly when you didn't even know he ate you in the first place, since he usually tries to eat you in situations where you're trying desperately to escape anyway. Lock the camera on Tahm, add a slurping sound effect, darken the edges of the screen, muffle game sounds. It should be unmistakable. As far as balance goes, Tahm lost a lot of the peel he needs to function as a tank. He's a vanguard, so his job is to stand with the team and protect them from enemies who get too close. Maybe add a burst of attack speed into his passive whenever he attacks an enemy champion, with a moderate cooldown tracked per-enemy. That way, he could more easily stack up his passive and stun enemies at close range, without needing to take Hail of Blades.
would also like to see some love for soloQ. He's been kept weak for ages because of his usefulness in organized play
