So as it currently stands, everyone basically has a preferred combat deck, where they spam their favorite color until their opponent is dead.
There is also an extremely small amount of weapons and armor used because there is no need to have 20 types weapons that all basically give the same bonus. Armor is a little better with the AGI modifier and soak values.
If, however, we have armor opening resistances and weapons opening bonuses, there would be a large content market available for adding new weapons and armor. We would actually be able to create a variety of combat builds.
Furthermore, to assist creating a deeper PvE experience, animals could have natural resistances to certain colors, encouraging players to have separate decks for separate animals.
I'm not sure why it's not done this way actually.
Please share any thoughts + suggestions
