I've been playing for a few days now, and I've got some complaints
•It seems you get no EXP at all when fighting units that are even just a few levels lower than your unit. Who thought this was okay?
•No matter how weak or disadvantaged your unit is, it should never be able to do 0 damage. Again, who thought this was okay?
•Exclusive quests for extremely rare pull characters. Who kept making these awful decisions?
I only have FF Brave EXVIUS to compare it to, which I've been playing for a month. Maybe DB Dokkan Battle and One Piece are just as bad, IDK. But IMO FEH is such an awful experience compare to BE. It's making me want to play the main games instead of this extremely watered down version, which I guess was the point, so hey congrats. I'll still keep playing though, maybe future updates will change these.
Edit: Maybe my first two complaints are also in the main games. I only played Sacred Stones and Conquest/Birthright, and haven't played any since beating C/B last year, so I most likely forgot. But for these time restricted games, they absolutely should have been changed.
