indeed, that would also make it less uber. That way people cant keep summoning each time their summon dies and kill all the melee fighters of the other side without a single casualty.
I do think each way needs to have 1 major summon (like balor or dragon on nvn) and 1 minor summon (like a wolf or bear) and some may even have some more.
It would also be nice to see all summons be differently and connected to their way:
-1 with a ranged shooter/magician-kind
-an other with a aid-kind (like a flying animal for any of your troops to help a.e. archers to get higher)
-a way has a elemental-kind
-4th is a melee fighter-kind
-a priest-kind
-
And i mean, that thus 1 way mainly has summons that fit in 1 of these sorts, so that the way you choose gives you acces to a specific kind of summons.
example: crystal is mainly aid-magic. Thus the summon of that way would be the priest-kind. That summon would not go into battle with the warriors, but intstead it casts out various buffering/healing spells to aid his caster (leaves you with more mana) and it would remain near his master to aid him in case of melee attacks.
example: red-way is mainly fighting/damaging. Thus that summon would be the melee-fighter kind.
This summon would just storm right into the battle and keep chopping till nothing moves, yet not going away from his caster for more then 100 meters to be able to run back fast in case of a melee-attack.
