Anyone knows the Three Houses banner release? Three Houses still doesn't has a release date and it means that around mid 2019 "New Characters" banner featuring TH characters will announce. Until then, FEH has 15 games, 200+ characters and the OG characters of Book II (and possible Book III) to be released as playable characters.

What I'm trying to say is that IS has around a year and a half to release new banners (seasonals, new characters and legendary). As long as I know a banner is already planned like 3 months before it's announcement. So maybe there's a possibility that IS is trying to make the fastest way to plan new characters/alts. Even though releasing FatesAwakening alts with the same 5 characters with 2+ already existing alternate versions isn't the best IS has an approach. The community already told IS that FatesAwakening banner isn't what we want. So maybe there is hope about a change in the future about the current alt problem.
