This game is great but but there are some major problems. 1, that the pvp is annoying because there's tons of hackers and not to mention the fact people charge at u and keep charging at u and using attacks and there's no way to escape unless you have a cover change unit. 2, Summon rates are ridiculous I have to buy chrono crystal's or grind for hours to get them just to summon and get the worst units of all time and it's fun to grind but I get bored after a while. 3, Zenkai units
