Is there any life in the idea that adding classes of Monster, such as Attacker, Tank, Support, Denier (much like what you would find in MOBA-style games), will add anything different to the metagame of Monster Legends?

Dungeon and War restrictions could include class instead of element/rarity/book. This could mean we fight in a war with DENIER/DENIER/DENIER.

This could easily be added to the game without too much stress, but I wonder if this is the direction SP want to go in.

We are working on something similar, but we have too many restrictions now, we will see if we add them as that.
But we are categorizing monsters by role.

@Carlos Can you tell what categories you use internally?

@Clackers I don't really consider tank a category. I think most tanks fall into one of the other categories. I agree that many monsters are tanky, but their skills define what they do. I think we informally already do that. but how do you classify someone like Laomu who has a deny skill, but seems at least to me to be predominantly support. That said, I runed mine like its a denier to run Global Doom from the start.
