Hmm idk. Maybe changes that would swap or remove tags I can see people being upset about and disrupting balance changes. But I think adding tags like UFU on chirrut or Rebel on JKL would be received positively. I always like it when the community mix and matches weird characters that just happen to work together to make something cool happen. It may not make much of a difference in the meta, but it would still be cool to be able to experiment more with them.
Recently, especially with the new bad batch, it seems CG has a particular team in mind when making characters and then they make tags reflect that. It takes away from one of the best aspects of the game: the ability to mix and match teams up to create interesting synergies. Again, will it make a difference in the meta? Probably not. But it would definitely be cool to see some older characters get more tags, especially since they make sense lore-wise.
