Best summerized as a game that will only be played because we currently dont really have a good lineup of f2p turn based stat. games. its badly balanced, on a garbage engine so bad you wouldn't even believe the number of glitches it has, with a very weak stategy component, and i mean weak. though in theory you have a variety of ways to play, due to the balance, most of the units are straight up worthless, and are better left unused rather then getting essentially a cannon folder unit.
Beyond this, the game is also rediclously complicated beyond my understanding (or it may very well be possible i understand it perfectly, yet the game is so buggy that i just can't even begin to understand whats intended and whats not) have a very very silly system of fighting. there are such awesome components to this game such as:
Calculations that lie about you having a 100% chance to hit, and you scoring a miss
Better chance of hitting your real target, by targeting the guy next to him, because reason
tons of skills saying they do one thing, and doing another
calculations telling you the wrong damage amount
sometimes not being able to activate the special warcall things (like defensive stance) doing your turn after movement, but then the other 50% of the time, you can.
within the last 7 or 8 months, the game has shown no signs of improvement, and actually seems to be doing quite the opposite, and getting progressively worse with each major update. i can't really recommend this game in anyway shape or form, but i can instead tell you this:
Go play fire emblem, even if its the gba version on an emulator, its still far superior to the experience you'll have here
