Hello everyone, and sorry for the wall of text I'm about to throw in your eyes ! (and another sorry for the many mistakes you'll probably find, english is not my native language, please forgive me...)

I'm a freemium player on nutaku and I'm wondering what I should do with my DC. First of all, here are my chars, and those I plan to level soon :

Black : Sybilla 58
Plat : Bashira 50CC70, Spica 50CC66, Sasha 50CC70
Gold : Iris 50CC60, Bernice 50CC60, Fedora 50CC60, Cloris 50CC60, Katie 50CC60
Silver : Valerie 50CC50, Mortimer 50CC50, Cecily 50CC29 (leveling her right now), Soma 50CC50, Alissa 50CC50, Elaine 50CC50, Phyllis 50CC50, Calliope 50CC50, Daniela 50CC50, Dorca 50CC50, Leeanne 50CC50
Planning to level soon : Claudia first, then Betty (50CC1), Shao (50CC1), Kerry (50CC1), Cuterie (1) and Marr (25).

To sum it up, I think I'm beginning to have quite a good core, but as I said before, I don't know how I should spend my DC... I have actually 310 of them and I basically see 3 options :
1) Keep something like 200 DC in case TP rotations come to buy any good unit and spend the others on awakening spirits
2) Do not give a single f*ck about TP rotations and buy more awakening spirits to awaken Spica, Bernice and Iris
3) Buy Saki, cause it's a black unit, cause I already got Spica, and cause even though she won't fit in all comp, when she can be used I see her doing the job quite well

I choose to do the 1) but now I can buy Saki, and I'm a bit lost... I don't think I should buy all the awakening spirits I can afford, due to the stats loss when awakening someone I'll need some time to level them up again, but if I buy Saki I'll be back to almost 0 DC, which means I won't be able to awaken someone anytime soon...

So, what are your thoughts on this ?

Subsidiary question : are 2 HA enough or should I take the time to CC / level up Bernard to have another HA ready, just in case ?

Thanks in advance for your answers !
