"Ratanah (U), is a good card but if you compare her to the 4 stars that are banned she is no where near as good"
This is what people don't understand..of course if you compare Ratanah on her own she's not ban - worthy. But alongside her teammates, which are horrendously solid, you can make a balanced half - deck for 12 - 13 stars with high power, SoA, decent damage, a couple of attack manipulators and maybe a DR. And that is just too overpowered for ELO, and so Ratanah is the strongest out of the bunch, so she had to go.
I think that in ELO we need to:
BAN Caelus & Shakra (whole decks have to be made to counter them or to use them, they affect the metagame way too much)
SAVE Wee Lee & Ratanah (for testing purposes like they did with Marco & Zatman, if they're still too overpowered then we ban them again).
I don't think Copper is ban worthy especially if Caelus is banned, it means he is easily nullified with SoA. The only problem was when both he and Caelus were unbanned because SoA doesn't work all the time.
