If a system could exist where you could assemble a weapon from components left over from battle and build monsters with perks based off of keyword abilities that were rarely used, would you use it? What would you want to see in it?
It sounds really cool, but the potential for abuse and overpowered combos in standard play seems really strong. Just imagining some potential Monster combos:
Fearbrand + Ethereal Hold + Ravage: Guarantee 2 melee attacks in a single turn against the weakest hero, ignoring positioning.
Stun + Ranged Attack: Used against a group of melee heroes, each monster could attack, inflict stun, and move out of range, making it very difficult (if not impossible) for the heroes to win.
Of course, the heroes could have similarly overpowered abilities, but this might create an unfun play environment.
I'd rather see this kind of thing released as a purely digital element for the Road of Legend app. That was the developers could adjust and "patch" overpowered combos, and in a cooperative setting having overpowered heroes isn't as problematic (I think it's pretty fun).
