Towers - Buffed for a year, Nerfed in a day?

Last issue for me to bring up, and this one I feel is fairly important as your Tank Meta is coming back in a big way:

Towers have been obviously, and blatantly, nerfed without any form of official word that I can find.

I actually had to do some digging, and it took quite some time to find various streams from a couple of years ago (and before) to find what I was looking for. Then I rummaged around and found RIOT's big, long, series of notes and podcasts concerning Towers becoming obsolete and what Buffs they were getting. They got those buffs.

They are gone.

-Exponential Damage Scaling per Hit -Fire Rate -Prioritizing Fixes -Base Damage/Damage Growth

These have all been reset to the second set of tower buffs out of, wait for it, six. In one year. Why? Your tank meta is going to come back, not in response to the assassin meta, nor the broken Lethality mechanic, but because you can walk under a tower at level five, again, and walk out once more. Just watched a Shyvanna, with zero tank attributes beyond MR Runes and Health in items, stand and tank both turrets at the Nexus in ARAM for.. wait for it... two minutes and eight seconds, all the while killing people that respawned because she had built two damage items. She was level 13.

While I do understand that no one wants to sit and watch professionals defend towers for three hours, and early dives are flashy and look amazing in streams... you are destroying the actual skill requirements of your game again.

Your E-Sports are, reportedly, running at a net loss. A stark contrast from when you started and you released an official video about the insane amount of money you made in the first two seasons. Do you want a clue as to why?

-Quick Cast -No Tower Fear -Broken Mechanics that encompass most every champion, so unbannable in ranked/tournament play -An entire new game style that focuses more on pushing through as fast as possible.

Basically, to summarize this lengthy idea:

Your Tournaments are becoming boring to watch because they do not require nearly as much skill or timing as they used to, and it -isn't- actually more entertaining to watch teams walk around in large groups murdering each other for thirty minutes. When these tournaments had flashy moves, quick reactions and counter assaults, and intensely heated chases through the jungle? They were fun to watch. Now it's "let's see who picks the better champions."
