i just say what i know ya.

actyi also not pro player. here still got lot pro player
fire hellbound u can train, if u can get fire inugami lagi best. combo it togetder then u can fight in upper wind againt wind unit.
ur wind garuda also not bad, good in stunt mobs. but in dungeons all big boss is immunt againt stunt. so better dont bring any stunt mobs to dungeons.
light garuda also few player favourite in areana bcos he can revives dead ally. after that nothing special about him.
for healler u can go to water fairy, but wind yeti also is good healer. wind yeti worth to awaken n evo until 3* 4*.
viking, i more recomended fire viking ratter then water viking. fire viking quite good in arena and dungeons.
wind mystic u better keep it. train her well, the 3rd skill can use to againt wind water epikion priest (rina) and even can fight well facing some dungeons boss.
