Hmm yeah Devout is a bit of a pickle to begin with right now. Most of the good light cards are summon only since they're so new... the ones in the ability shop aren't worth investing much into since they're the most basic. The FF VII Remake card (Jessie) is very very nice for Devout, but again... it could possibly take 4 summons to get (though you'll probably hopefully get something else decent along the way too). How far along in the story are you? I can't remember exactly how many summon cards you get for clearing story chapters, but they do add up pretty quick (though some of them I'm remembering could be from old events as well). We're also getting free summon tickets for that special login right now which is nice.
I think I got almost 2 million of every seed except dark (don't have any 5* with dark seeds yet) just today. 4x bonus is craaaazy! So easy to just give it a poke or two while I'm working, kept it going all day.
I'm not very far through the story at all.
How long does the draw event go? I'll hoard my tickets for now and see what I end up with. I've been doing mako reactors. Just finished 1. Devout is WAY stronger than the starter classes even with a couple crappy 3* fire and water abilities.
Just got enough ability tickets for hermes. Going to grab that I think. I keep reading that's a great card to have.
