Ok so I'd like some recommendations since I don't know much about the game right now or even worse how it's gonna be in the future:

First of all I got an account with:
WATER: Ryu-Oh, Aphodite
WIND: Gaia, Odin

The second one:
WIND: Hastur, Titania, Jabberwock
FIRE: Mars

For the first account I've been grinding and grinding but even after getting sniper shot and slowly but surely getting a full grid of SR assaults the damage doesn't really go up, also there are almost no people with water Eidos to help me and when I get someone they don't accept since I only have diabolos and a Ice Disaster to offer ^^
The good part is, this account already has lots of good SR himes, so basically I have a functioning Wind and Water team, two elements that compliment each other perfectly. Bad thing is I'm basically without Eidolon. But I know a water raid with a nice Eidolon is coming soon.

The second one is really a baby, but it's fun to play, peak damage is already looking promising, and I don't have that much difficulty finding friends, bc of Jabberwock, also having Mars in there already gives me a core hime for a second Element which is nice, specially bc it already has like 4 Belial friends, which make life really easier.

Now to my question:
I only have the possibility of one Miracle ticket, I I wanna spend it on the best possible way,
I'm thinking I could use it for the first account and get Cthulu and my water team would be really nice, even though I'm still not sure abput the damage, maybe after getting a MLB the next raid event I can hope for good friends.

My second option would be to use it on the second account, probably on Gaia, bc it's the best available Wind hime right now, but I don't understand how Wind works without a healer right now, is Wind even worth it without Cybele and Seth?

Anyway, I really don't know much about what is possible so every input would be appreciated ^^
