@scarletgamester Ofc it is worth it man, you have 4 spirits with 4 skills each. Some are dmg skills some are supporting but every 1 have it`s use. Usually warrior use them more because have lots of rage at disposal (i almost every game make 30-35% overall dmg with them, not counting usage of supporting rage skills). If you are new to this game, give them a go and see how it turns out, but trust me they are worth using.
Have fun
