It is a suicide to quit and come back in a gatcha game.
It could be a nice idea in a mmorpg, but it's horrible right there even only for a matter of premium stuff that you lose without doing quests/log in/events.
There are many games like i said already above, 7k/valiant force, that from day one had:
Guild vs Guild, story progression, pvp, raids, hero events, boss events, defend castle/attack castle mode, climb the tower... i could go on and on, but there is no sense if you don't know the games i'm talking about.
Some sh, decide to develop the game for few/many YEARS before releasing it even only on 1 specific country, because they want to be sure to be ready.
If i have to be honest, FEH seems to be a project made in a year or even less than that.
