League of Legends just released a game mode called Teamfight Tactics. It is played through the LoL client, using LoL assets. Someone has created teamfight-tactics and it has 3 questions that I can see. Should we create a tag synonym and point it to league-of-legends instead?
I don't believe we should make it a synonym for league-of-legends as the game play is vastly different for TFT than for any other game mode in League of Legends. It is essentially a different game, it just so happens to be playable through the league client. Given that we have precedent for this in other games such as Fortnite, GTA V, TF2, et cetera, I would say we should keep the separate tag for the separate game.
I definitely agree with @Dragonrage's answer that those should be two different tags.
I've played a lot of League but I haven't touched TFT so far. When I first read some questions about TFT I was extremely confused about the things being asked here.
Adding TFT as a synonym to the existing LoL tag would cause a lot of confusion since the characters and items are the same but the strategies and the gameplay itself are completely different.
Having two different tags will allow for easier distinction especially if someone chooses to ignore one of the games.
