Making combat rock-paper-scissor like and adding "combat credos" that most of fighters will be too lazy to even get is a good way to remove PVP from this game completly, surely would work for me.
In my opinion currently it works well with some people using swords and most people using b12s and pretty much the same using the same deck, I feel like in a permadeath game "PVP meta" is actually good, atleast the fights are fair. I can't imagine losing a character I spent months on to someone that has lower stats and is a worse fighter only because his gear/deck counters me.
