I've been playing for about 2 weeks and my team is at present composed of Cybella,who in turn I have linked to Luna and Aaron with Theia and Lucille to provide healing support.
The problem I'm encountering is that my team is extremely squishy,as the boss in Chapter 24-3 made me very aware of when he demolished my entire front row in about 2 turns,before I could
take him out. I've been trying to improve there defensive stats with equipment upgrades,fusing, and runes but I'm reaching the limit there as well,as I did try the Heroic version of the event for better runes,and I couldn't damage them fast enough. I do not have many other options,hero-wise,as most of my other ones are either mages,or shadows. I've been going through the other missions on heroic to get as many gems as possible,but is there any thing I could do to improve my team? I have been grinding for the relics I need to upgrade Cybella and Lucille,but that's going to take a while,and I'm not sure if that's going to be helpful at all.I've also been working on limit breaks for both Aaron and Luna.
