Future Classes for TFT? *Ideas

Hey! I've been enjoying TFT alot and wanted to theory craft some future class sets! I have 26 1st place wins under my belt,... not sure if that's a lot or not but i feel proud about it :) any... i have two ideas for future sets. Fire maybe call it Pyro : Ability can either burn units and if having 4 of the 5 units they can lower the freeze effect versus glacial for your whole team. (Fire and Sorcerer) (Add Fire attribute) (Fire and Brawler) (Fire and Elemental) (Fire and Yodle???) 2nd future set it. Cosmic: Having 2 Cosmic units slows enemy champ movement by 20% having 5 Cosmic units slow enemy champs movement by 50% and your full team get additional attack range. Champs could possible be: (Cosmic and ????) (Cosmic, Blademaster and Knight) (Cosmic and ????) (Cosmic and Sorcerer) (Add Cosmic)

I'm don't know the lore for the game fully, so if you have any ideas or changes for the buff they get just leave a comment! What do you guys hope to see that they add in the future!?
