Azir, janna and Kalista are being nerved into the ground.

These champions are soon going to become completely useless, even in the right hands. Competetive may be abusing these guys but I haven't seen a toxic Azir, Kalista, or Janna in months.

They're becoming over nerfed in my opinion.

Azir's only passive is borderline useless. A high CD temporary tower every 5 minutes? Towers in general are a joke late game, so this passive is only useful if you lose or take a tower very early. Very late, the passive would be useless even if you could spawn towers every thirty seconds. His E is no longer an offensive ability, which makes his play style very awkward now. It essentially makes him a mobile zoning mage with one damaging ability (Q) and the hope that superior kiting skills will net you a kill. They need to remove his sieging ability on towers. If they want to take away a strength of his, take away a useless strength. Azir is a mage, He should have multiple forms of CC to get him by in a fight, he doesn't need sieging potential.

Janna's only problem was her ridiculous amounts of disengage. She was untouchable. But I found her reworked passive to give her the weakness that she needed. Jumping on to Janna is much more possible these days so I don't understand what the big deal is. If you nerf her damage or her ratios, Janna players will just build tanky. ATM she shares a similar play style to Sona so I'm not sure why her competitive play is making her toxic.

They said Kalista has solo carry potential? HA! Kalista can't duel anyone unless she's incredibly fed, even then she's fighting without two of her main damage and peel abilities. Her passive has been nerfed to the ground since launch, if anything, it's more of a hinderance to her. If you ambush her and jump on her, she's not getting out. She needs her entire team to keep her alive. They need to focus taking away power on her E. It's a toxic ability, me nor my opponent know when it is capable of executing someone, and when it does there's not a whole lot of counter play to it. imho they need to direct power away from her E and shift it to her Q. Q should be her main damage, a skill shot that is also her only extra get away. That will give Kalista players a meaningful decision on when to use it.
