After the release of patch 10.9, the strength of many 1-cost champions has significantly increased, simply because they can be upgraded more easily, even to 3 stars. Additionally, some champions have been directly buffed; for example, Ziggs has had his damage increased too much, making him even stronger. It’s quite normal to “get wrecked” by a full team of 1-cost champions all at 3 stars in this new patch.
Perhaps Riot Games does not want the “donkey-roll” meta (which could be translated as random rolling to get 1-cost 3-star champions) to become popular because Teamfight Tactics is ultimately a strategy game, where players need to build their teams stronger over time rather than just relying on 3 stars to crush opponents. For this reason, in the latest updates from the PBE test server, Ziggs is the first name to be heavily nerfed, and he may not be the last. Specific changes include:
Vel’Koz
Skill damage increased from 425/550/2000 to 450/600/2000.
A direct buff for the Sorcerer and Void team compositions since Vel’Koz is a key champion for both of these teams. Magic damage compositions seem to have weakened quite a bit after the nerf aimed at the Star Guardian previously, so even though Vel’Koz has been buffed, the issue still entirely depends on the item Tear of the Goddess.
Kayle
Skill damage decreased from 125/200/750 to 125/200/600.
The update barely affects Kayle’s strength since the damage at 1 and 2 stars remains unchanged; very few players have the luck and economy to upgrade this celestial maiden to 3 stars. Perhaps Riot Games does not want Kayle at 3 stars to be an auto-win champion anymore, which is why such adjustments were made.
Ziggs
Maximum energy reduced from 45 to 20.
Skill damage reduced from 300/400/700 to 70/120/200.
Specifically, Ziggs’s damage in the next patch will only be about 23-28% of what it is now; even reducing the energy required for his skill to just 20 is not enough to compensate for such a heavy nerf. The only way Ziggs can be effective now is to have a Blast Charge buff, use his skill, and continuously stun opponents because his damage output is too weak now.
