Hi PB,
I would love to see more customisation of heroes in this game. Currently the only way to customise a hero is to add a friendship disk and that often doesn’t change the way they play or can be used, much.
I would love for there to be a way to equip (and also remove!) artefacts or special equipment pieces which have specific effects - like a magic wand that turns a stun into a silence for example - could be equipped to Maleficent to then add to her synergy with Tia who has the Yax disk.
Alternatively full sets of equipment - head, body, legs and boots etc. that equipping all pieces of the set provide a particular bonus - Immune to Curse 1x per match/wave etc or triggers Regen ad 25% health and heals XHP per second.
There are a lot of ways that could be implemented alongside the current system. I think it could be used to change the way that particular heroes/villains could play or be used whih may tip the metagame on its head.
Those are my thoughts, at least!
