werfer and caliope are fine because u know there is something like asymetric balance i guess and its like pershing and king tiger
You know what assymentrical balance means?
King Tiger:
Armor, health, AoE, damage, penetration vs speed, slow turret, cost
Pershing:
AoE, speed, pircing shot, reload vs health and armor to some degree.
So when you compare KT and Pershing, both of them have some advantages. KT has better armor and main gun but it's slowr and easy to flank by Pershing.
What about Calliope and Werfer?
Firesparks already said everything. Less rockets, less damage, less HP, less armor.
Assymetrcal balance in this case should look like this:
Calliope: armor, health but shit long-mid range damage.
Werfer: shit armor, shit health but very good long-mid range damage.
Currently Calliope owns all advtanges.
