Many people see 3-4 stars units only like fodders, but i think is really a shame to not make more usefull this units in a way that people could be happy even if they make a gatcha and don't find a "possible become 5 star unit" even because devs has work a lot even to make this units that may seems usless to many.
I know that in the future some 3-4 stars units may seems upgrade, but i think that it should be nice to see support heroes stay 3-4* but with really unique abilities.
Dev could change them skill and aura in a way to make them really usefull.
We know already that 5 star units have stronger stats, and skills, then why don't make 3-4 star units more like "support" team companions?
I make some example:
X 3 star unit.
Bad stats, but her passive make drop double money if the hero on her aura kill 50% of the enemy or more.
It could seems op, but in the end you have to make her survive until the end to make her skill work, and it's not a easy work

X 4 star unit
Passive aura make take double experience to the hero on near her if the units survive until the end of the fight.
The tactics possibilities in this game are endless, then why don't put more idea on the overall structure of the game?
I know that all Units have a job/work and that it could be strange to see a thief make double money their team on the end of the fight or a mage make double experience, but in my opinion it could be really cool.
And please..
Make that girl in the hero selection on the top corner a grabable Unit, her artwork is too much great to be only a npc on the background..
