Oh, they finally caught that Cidd bug where his S1 was sometimes still upgraded after his buff dropped off. I want to say it only happened when you were transitioning between waves of a stage, or maybe that's just one of the only times that buff is likely to fall off since Cidd is constantly using his S1. Either way, not too big a deal.
As for Bellona, I got spooked by Vildred so I'm fine for AOE greens. But I'll roll a bit anyways because it's Bellona.
For the record, while Angelica is arguably superior in Abyss content, the same is not necessarily true of the endgame raid content. Most raid bosses have some kind of buff removal, which utterly destroy's Angelica's utility in those encounters. Additionally, if you use her S3 as a preventative measure, you only get the barrier/immunity side and lose out on the healing, which is a tremendous loss in efficiency compared to Destina or Achates just healing everyone *after* the enemy applies their debuffs (and both of those characters have much greater scaling values on their S3 heals).
At some point you're probably going to want to switch from Angelica to Achates or Destina if you're lucky enough to have two of the three. It's just that type of game. No one character is the perfect answer to all content (unless you're Diene).
yeah...I don't regret my skill point investment into Angelica since she is essential in Abyss, and I still use her on at least one raid boss. But Destina is who I'm focusing on. I used Achates as my main healer for a long time and while I miss her short cooldown S3, the invulnerability got less valuable as Ravi became nigh-unkillable and my team got faster. Destina's insane heal output and combat readiness manipulation, on top of her fat HP bar have been huge for me.
I've spread myself too thin across those 3 AND SS achates (for pvp) and I kinda wish they'd let me recall some of those molagoras. But it's not like I haven't gotten tons of use out of them. Maybe in the future they'll have modes that require multiple distinct teams - I think they mentioned something like that.
