I'd like to see Henchmen that're added to the Crown Shop that do a single type of gimmick, example: Life Henchman that ONLY Heals, Ice Henchman that ONLY Shields, Death Henchman that ONLY Traps, etc.
If this isn't possible, I'd like to see the inclusion of a control system to let us, the player, control what spells Henchman do in a Duel. There could be new henchmen designed specifically to control while allowing the cheaper alternatives to remain in the Crown Shop, perhaps even alongside the Gimmick Henchmen.
This'd be like a Henchman Overhaul and would allow players like myself who despise playing with others as most people can't keep to their own class structure and spam attacks, traps, support, etc., a chance to thrive and pay into the advancement of the game.
It'd be nice to see some of the older retired Henchmen come back too. We want our Calliope WordTamers and Ravenna Lightwraths back!
