If I were in charge of Woolim or Yuehua, I would have added Yena to Everglow and Chaewon to Rocket Punch almost instantly. I DEFINITELY wouldn't have given either group a comeback right around the time of Iz*one's disbandment. I would have given Iz*one members time to be like: here's the deal, we're adding you to the team and we'll prepare for a comeback soon, let's get to work. Both groups have been on hiatus forever and made a comeback at the worst time possible. I don't know if they will even get added to the groups, but I think they could really help. Everglow especially has taken a big blow to their career with this hiatus. They had an international fandom that was almost as big as LOONA's and I haven't heard hardly anyone talking about this comeback. Meanwhile I think Rocket Punch could benefit from having another main vocalist; I think thats what they're lacking. And yeah, people will complain about them getting added. Who cares? People will always find an excuse to complain. At the end of the day, the groups will (likely) experience a massive boost in popularity with the addition of the Iz*one girls.
Do you think Rocket Punch or Everglow will add members? Do you think they should? Are there any other reasons you think both groups have experienced declines in popularity?
