agreed... need little bit luck too
centaur... forget about it, if you trust me dont ever train him... when he came out, he is strong... magic team scare of him, but when magic heroes reach purple +4 / orange, Centaur become expired lol, his shield when enter battle, no longer superior... low damage, shield once (is once, Lucas can block physical dmg more than once with his ulti)
after monkey hero come... he become blur already

Centaur need alot dragon heart, about 5 to reach orange (this item not easy to farm, need 50 pieces of axe to combine), Purple +3 need 1. +4 need 2, orange need 2, definitely not worth invest him IF you dont want spend real money
Leo and Vincent perform a lot better than Centaur in COF and is a lot easier to reach orange
Leo is far better than Centaur after all... survive longer, crowd control skill better... assist better...
Wah u r like a crystal ball to us. Thanks mate.
