What's your main team? As much as I love Cheery she doesn't fit most soldier teams, since there are a lot of mana issues that steem from fielding a 2-mana mage (to hell with getting either 3 or 1 purple mana), but she owns in the Colo.
Musica is a great fit but only if you can count on your friends to provide event characters. Her role is having a pocket event-character ready (through her skill, by nearly doubling the stats of a friend's EC) for the hard waves of any given event.
Lilith is too good, but probably best to get on a fest, Holy Capital's characters really don't do much for a soldier team... although you have Lephret, so it isn't that bad.
My "main" team would probably be LB3 Selene, LB3 Coro, MLB Trystan (the F2P triad), and either MLB Melvina or LB0 Arietta, with LB0 Phoena (LB1 if I finish all my CSQs) and LB0 Juliana in sub.
My core party's fine, though some of them need leveling; I'm more focused on finding specialists (and chain stories, to LB Phoena).
I keep working on leveling characters; demon raids or high level (50+) quests are the only time Coro, Selene, and Juliana come out to play now.
I've made weapon diversity a goal, so that I can have a decent party for any DR, which was a boon in last week's raid. Having LB2'd every demo since Coro certainly helps in that department.
-Aludra or Cheery offer a full-screen nuke, and can be key members of wand-based DR teams (to say nothing about PvP modes), especially when paired with my LB0 Filiana.
-Musica would be a cornerstone for a dance team build for future DRs, alongside Frau...plus my 7th CS.
-Lilith would be as good a healer as I can get (having flailed in futility during Mei week), plus A CS.
-Archers or - oddly enough - blade-wielders are the one area where I could use a good 2nd or 3rd option (6k+ attack) for future raid weapons. (Juliana has the Volunteer sword, so she's out of the picture until v.2). An archer whose special shoots multiple, random arrows (like Bliza) could be a poor man's Aludra / Cheery.
- Weaponsmiths are more of a fallback (if/when I don't get the character I want) than a reason to burn tickets at this point.
- My only other goal would be to get a non-Cleric healer (Elemia, Linea, Yona) to build a ranged team around...but that's a secondary goal at best.
Until I can decide on a direction - or there's an offer I can't refuse (e.g. The 5x rate up for a CSQ character like Filiana) - I'm holding on to my tickets...and trying to level the characters I have. Definitely waiting until there's a festival with improved recruitment odds before doing anything.
