Can someone please explain to me why Gferus card is worth so much? +1% HP? Woo that hardly makes it worth almost 4x as much as Matyr. Gferus are not hard to kill and there's a lot of them on their map to so access to them is not difficult. /retarded.
more with how easy/difficulty it is to farm... green ferus maybe easy to you, but not everyone. Matyr is certainly easy for almost anyone who job changed. Comes on a map with zerom and etc too.
Green ferus... you really are going there just for green ferus. Red ferus is decent, as is penomena, but certainly more challenging, require a lot more equip and the other card options that accompany green ferus is not as high end competitive as the friends that matyr come in (well, or maybe just zerom but that's a big one.)
Setups/dungeon designs like this make it more likely so people get a matyr than green ferus. As for if this really makes up for 4x the price, that's up to you to decide.
