For the good allignment, all you need to do, is max out affinity blast and crippling mist, upgrading the sun/moon stats as high as you can go(only like 10-20 power upgrade) and you can kill most enemies in one shot, 2 at most
OK Heres a summery: Humans have an alright, sick lookin titan, and the best final regular unit(paladin). Orcs have a GREAT 2nd mage(totem) one of the best units before you get the angel/devil to juggle the enemie's smaller units. This can single handedly beat most battles coupled with a bunch of beast mounts. The orc's titan sucks, little damage capacity and its small :[. The Elfs are probably the best. They have one of the biggest advantages to start with: The elemental arrows... actually do somthing. They freeze most of the enemies, which is a great time saver. Then, the final regular units(Protectors) have the highest damage capacity of all of the regular, but are slower moving and less reach than the paladins. The elfs have the best titan IMO, because it has a long lasting effect, and attacks twice, fast in between. Angels help immencely, and mass 2nd mages(totem, wizard dryad) also can change battles. If this helped, copy n repost.
