True, deine isn't a high priority, I mostly just plan to level her eventually due to the use of a tank that can deal damage when I don't need to worry about being quite as tanky as Gellius can be. Not really a priority though as you said. As for leveling units to max, while I do plan to do that eventually, I usually try to take units to level 40 or so, then move on, while coming back and leveling them as needed when not focusing on a unit that either is needed, or fills another role.
She is one of the main contenders I have to awaken if due to being both fairly decent on her own, min costed, and her skill. That said, as you noted, I tend to only use a few golds due to having better plat and black units most of the time, so while her awaken ability is useful, it isn't as useful to me as it could be. Still, barring unexpected developments she is likely going to be awakened sometime soon. Just need more witches and one more unicorn knight orb.
Yeah, with Odette and Sasha I've not really felt the need for another mage above silver yet. Usually I use Pallis if I need a cheaper one, and the two plats work well if I need damage. Zola I mostly just use for the Demon Crystal G map final wave.
Mostly I've been putting off awakening him as for all that he becomes the best tank, he's presently worse than my Bernice with min cost and max skill level (compared to him being max cost and level 1 skill). For the time being I plan to wait and awaken him once I have some more rainbow fairies to boost his skill.
I have at this point awakened Aisha, as she was only waiting on one black spirit to max when that screenshot was taken. That said, I'd previously been considering holding off on leveling her post awakening due to the chance of one of the upcoming events having a fairy to take a black unit from level 1 to 99 post awaken, but in thinking on it and looking at her stats, I notice she only gains 106 attack over 99 levels, and wonder if it wouldn't be better to just level her to 50 or so and save the 1-99 spirit for a unit that benefits from being max level more?
I suppose I could start on leveling her. I'd somewhat put it off due to already having Despara, but the 10% health is attractive. That said, is she worth cost reducing, or is she mainly good for her awaken ability? Because I've got two extra in one of my boxes. Either way, she'll need to wait on getting more witches to CC and otherwise take to awakening.
Thetis I've been planning to try leveling and awakening to have a good valk, but largely I've put it off due to generally preferring to use princesses. On the other hand, I've got 3 extra copies of her that I could use to CR and skill up her which may be useful. Cuterie I plan to awaken eventually, but I've not really been hurting on affection items for some time, so she hasn't seemed a huge priority. As far as Lyla, to be honest I've never really used bandits, so I've not really bothered with her yet. I'd certainly have leveled and awakened Cellia, but alas luck has not seen fit to give me the spirit booster (not that I can really complain about what it has given me). Rika and Claudia I plan to awaken and level eventually, but at present events and the like have not resulted in them being a priority.
