Electro with water is persistent damage.
Electro with fire is overload.

Both are very good damage and you're guaranteed Barbara still, who should be in your team for difficult content anyway. We have both Amber and later on the Chinese chef girl for fire users, so she's going to mix very well for F2P.

I was ready to ignore this cuz the first word out of peoples mouths when talking about this game is Gacha but my girlfriend heard about it and apparently does not care and wants me to download it

how in your face is the gacha stuff?

As others have said you can largely ignore it. As long as 1) you aren't intending to do a lot of pulls and 2) you don't cave to "oh that's a lot of nice bonuses you can get" syndrome, you'll be fine. The game is F2P friendly, especially with the free units and currency they're giving out.
