Vex
Stubborn, non-small damage and the ability to create too strong shields are the most powerful points that Vex possesses. Even the appearance of Vex made the Mage squad extremely powerful without the need for any pure resistance units. Combined with the ability to improve the economy from the Yordles, Vex will help gamers build squads extremely easily. So it was only when Vex was heavily nerfed in the ability to create shields that the Mage squad no longer raged the meta.
Vex will reduce the value quite a lot because a series of champions capable of approaching the backline are about to appear
However, in the upcoming mid-season update of Teamfight Tactics, Vex’s resistance value will be greatly reduced. The reason is because Riot has added too many champions that can attack or close to the backline without the need for the Assassin system. The most obvious example is Irelia, Tryndamere when they have the ability to dash straight to the back row or like Sivir to deal damage to multiple targets. This makes no matter how “buffalo” Vex is, it will not be able to endure for the whole team as before.
Seraphine
If you are a player who specializes in playing the Inventor squad, you will know that the strength of this team-comp is the ability to heal and create continuous shields. So although the number of units that can withstand is not too much, they still last a long time in combat. Even with a fragile backline main form like Seraphine, thanks to this large and constant regeneration, he can become extremely stubborn. As a result, the Phat Minh team in season 6 is a comprehensive defensive team, too difficult to counter.
Team Inventor will no longer be so powerful in the upcoming 6.5 season
However, when it came to season 6.5, this strength was greatly reduced when Taric was deleted and many options for approaching the back row appeared. Taric’s “discoloration” caused the Inventor’s squad to lose its strong resistance in the middle of the game, while the recovery ability of the replacement – Senna was not too impressive. As a result, this squad’s frontline can be killed too quickly, not even giving Seraphine enough time to heal and reduce value quite a bit.
Kai’Sa
Once considered the strongest unit “the flag of dignity”, but Kai’Sa had very little acting space in season 6.5, at least on the test server. The first reason lies in the fact that Riot keeps the 4% rate of appearing 5-gold champions at level 8 in the upcoming season 6.5, so it is extremely difficult to roll out 2-star Kai’Sa. This makes it easier for players to switch to using 4 gold key champions because you can raise them to 2 stars more easily.
Despite not being nerfed directly, the 6.5 season meta doesn’t support the main use of Kai’Sa
Besides, the appearance of many strong 2-3 gold champions like Tryndamere, Corki, Syndra in season 6.5 will make the reroll gameplay much stronger. Obviously, in a meta that doesn’t reroll a 3-star champion and also uses a 4-gold 2-star character, it is extremely difficult to push to level 9 and use Kai’Sa as the main force. As a result, Kai’Sa almost completely disappeared during the beta phase of season 6.5.
