would be nice to have different sets of equipment or something like that. Where you fighting a fire boss and you equip water damage weapons and armors. or have different spells to buy, you can buy like for the wizard ice, fire, water, earth but only have 1 active spell at a time.

Environmental buffs - Say, Merman can have a DPS and Health/defense increase when fighting in a Ocean/river/lake/beach area. Fire Phoenix gets a boost at volcanoes or in the sky. Jim the Lumberjack gets a boost in the mountains. Artaxes, the Lion a boost in Africa or jungles. Princess at castles. Jason gets a boost in the dark, WW on a full moon, lol. stuff like that.... it would be nice to see different areas give better buffs for different heroes / crusaders.
