How long will the pro-play overbuffing continue?

Hello,

I'm here to share my concerns about the Leagues balance team decision when it comes to converting a champion into a pro-play viable one.

Some classes aren't as favored in League pro play as others. For example, when Sion and Urgot get nerfed, two more tank champions will take their place. When Ezreal gets rebalanced again, another ADC will take his place. This happens because ADCs and tanks will always be favored by pro players. When it comes to assassin's, assassin's will only be picked when certain champions are completely out of balance. You already know where I'm going to with this. In order to force Akali into pro-play the balance team decided to make her virtually immune to poke, tower dives, and "out of position" missteps. Same for LB, Pyke and Irelia in some part. And it's not with any disadvantages, they will still 100-0 a squishy champion, they will still be almost impossible or not worth to gank, and will mostly likely walk away if caught out of position.

How long will the balance team continue to force champions, especially assassins, into pro play with either inbuilt sustain, aoe stuns and/or slows, multiple dashes, complete with aoe point & delete abilities and defense/"get out safely" tools, or the massive buff bombing that Lux got to force her into pro-play (although the Lux pro-play experience didn't work)?

I'm not talking about nerfing those champs, I know that once they get released in a broken state, their players feel like they belong somewhere since they can now feel useful without putting much effort. I'm asking when the balance team will stop purposefully release champions in long-term unbalanced state just for those champs to establish a solid playerbase through favored pro-play presence.

I'm making this post out of salt, tilt, and overall a certain feel of unfairness for the last couple of years, seeing my favorite champion, Azir, getting nerfed to the ground in order to make room for the more casual friendly champions like Yasuo, Akali and the rest mentioned above. At the time when Azir was getting nerf after nerf, he had lower than 47%wr, while Lux had around 50%wr and she was still getting buff after buff just to force her into pro-play, that's also close to when the Irelia rework happened. Riot said they didn't want another balance nightmare like Azir, Ryze and Kalista, yet they knew what's gonna happen when they chose to release the reworked Irelia and Akali and revert LB and Rengar back to point & delete state.

I hope there are people who are willing to participate in this discussion(and not just get downvoted by Akali mains). Am I imagining that the balance team is forcing champions into pro-play, or they never thought that releasing Akali with such an overloaded kit would make her a dominant pick?
