I'm staying away from it depite the tactics style gameplay sounding pretty cool. I hear its ridiculously grindy and not at all friendly to non spending players.
Eh. It's pretty generous with the currency, from what I've played (which is very little). It seems like you pretty consistently get stacking daily login bonuses adding up to about 800 Visiore total, and a 10-pull only costs 2000, so you can probably do a 10-pull every few days when you factor in rewards for actually playing.
For the record, I've barely touched the game apart from collecting login bonuses and doing free pulls, since I didn't want to invest time into the JP version when a GL version was coming. I haven't even completed the first chapter of the story. And still I've managed to get a pretty decent assortment of UR and MR units.
The rates
are pretty low, but you seem to get a lot of opportunities to pull, and they don't release
anywhere near the number of units that FFBE does, so it doesn't seem that bad to me. And when it comes to materials for awakening and limit breaking, you can farm those, so at least it's not just restricted to getting dupes from banners. It also has a VIP system, but I'm pretty sure you can earn VIP points without spending, so F2P can get those benefits with a bit of time.
I've already invested a lot of time (and a
little money) into FFBE, so I'm not looking to fully dive into another gacha game, but I
am planning to play it the same way I play
Opera Omnia, which is to do the story and collect login bonuses, and then spend my hoard when a character I like shows up on a banner. And for that, it seems like you earn a sufficient amount of currency from casual play to not have to worry about hitting any walls.
