Title sais it all. Not just explore, but the monster hunts should reward us with the same amount of cards, cause honestly…it’s more time sinking than exploring.

but there are multiple types of monsters per map, so overall monster hunt is about same (or even better) than exploration.
killing 100-300 monsters that has 50k or more hp and deal 1-2k damage is not exactly fun though
That means that 3 card / monster type is fair. There are smaller and bigger maps to explore too. 
So yeah… I think it would just make it worth it to get 3 card / achievement too.
2 per map exploration, 2 per monster then - still a net gain… for the sake of Balance (do you want faster leveling for bots?).
