Because
In the first half of the Teamfight Tactics season 6, Vi is a not so prominent general whose main task is to increase damage to the Gladiator squad thanks to his ability to subtract armor. In addition, with the price of 2 dollars, it is difficult for Vi to compete with other stronger units that improve better at the end of the game like Kog’Maw or Trundle. Even with the Sisters activated, Vi is not a very strong piece, instead, the support will be slightly better.
Vi will be an extremely remarkable 4 money champion in the new season
However, with season 6.5, Vi has been increased to 4 gold and has a skill that can deal damage and control opponents much better. Moreover, with the introduction of the Swift Justice technology core, Guards generals like Vi will be able to deal much better finishing damage. Besides, in season 6.5, the game speed has slowed down quite a bit, so 4-gold champions like Vi will have a lot of opportunities to level up and win.
Swain
Contrary to Vi, Swain has a rather “tragic” fate in season 6.5 when this piece is no longer as important as it is now. The reason is because the Empire race has been removed and Swain can no longer “hack damage” and blow up opponents as easily as before. Next, Swain’s new race – Hextech seems to have an effect that is not at all compatible with the character’s magic damage nature.
Swain now only plays a activating role in the Hextech team
Basically, the Hextech race has a shield effect and during this duration, the champion will deal bonus magic damage on hit. However, Swain is a champion that deals strong magic damage to recover, so he doesn’t pay attention to stats like attack speed like Riot. As a result, this unit is often replaced in the Hextech team when the player begins to complete the formation with Hextech and Striker pieces and does not need an average tank like Swain.
Talon
Basically, the way to play Talon in season 6.5 is still not much different from season 6 when this unit still needs items like Infinity Sword, Alchemy Towel, Lien Thanh Cannon. Although he also loses the Empire effect like Swain, in return, Talon can deal extremely good standard damage thanks to the VIP effect from the Idol race. Therefore, Talon becomes even more dangerous in the early game when the enemy champions do not have the ability to protect against great resistance.
Despite changing races, Talon is still too dangerous a chess piece
Another thing that makes Talon become more and more valuable in season 6.5 is that other units like Shaco, Akali are deleted. As a result, Telon from just playing the role of a type of attack unit, contributing damage has turned into a very strong main force in the early game. It will not be too surprising if in the upcoming season 6.5, the Assassin team is still an extremely strong reroll play with the main character Talon in a 3-star state.
