@Riot - How did you "buff" Tahm Kench?

When I'm not playing Yorick and/or when I play ranked, I play Tahm Kench Top... I would like some clarity.

Today's patch hit me in the feels. Tahm Kench has been my "I'm comfortable with this champion and my ability to play him" pick since shortly after he was released. The game has always been "play till 6, then kick lick 'em where it hurts."

Since he was released, several things have happened to TK: His HP% damage on ult was reduced, his (already useless ult) received a delay before recast, then today. 1-HP% was further reduced by a LOT -- from 6% to 1.5%. I read somewhere that acquired taste stacks and causes more damage... This puts it at 4.5% after several moments and lots of potential damage is past. However, I guess movinh the %HP damage to passive from ult means you technically buffed levels 1-5. Albeit, while nerfing 6-18. And that's only to champions! You still majorly nerfed damaging minions and monsters! 2--Patch notes say Q was buffed, though it didn't feel like it changed at all in the two games I played since patching. This could be due to the previous point, where we discerned that TK's damage was nerfed today. 3---Devour wasn't changed. In fact, I never recalled any big buffs or nerfs to Devour so I checked the wiki. It was nerfed near the beginning of Tahm's existence to remove the additional movement speed when devouring an ally champion and retreating from battle. 4----Thick Skin no longer grants 100% Grey Health, but it felt like the heal kicked in a lot faster... And the active disappears after 3 seconds instead of fading over 6. The active bubble can be cast a lot more frequently, (from 16-12 seconds to 6, now) but it is overall much weaker than it was. At literally every level, E is less of a shield and less of an heal... But I can do it more often.

The range on ult was increased. When TP is down, I use it to move a little further and very infrequently I also use it to go into a fight of some sort. The cast delay that was implemented so early on was cut from 1 second to a quarter second, so it is easier to use as an escape now. The warning time was decreased... But what do my enemies have to fear anyway? I'm like a catfish with...Baleen is what whales have, I think. Baleen's not terrifying.

In what universe did you buff TK? My damage at every point in the game is down. I guess more frequent bubbles as a support can help, so you accomplished your support buff. However, you did that at the cost of absolutely destroying Tahm's damage output.

To restate my question: How do you consider this a buff to Tahm Kench when I (very clearly) consider it a nerf?
