Personally I feel like having most quests reward the player with experience makes them follow the same linear path every time. Thus, I think that the game would feel less linear if only a few quests had (bigger) EXP cards as rewards, and most others would reward items and equipment, making the players go out of their way to look for leveling routes (so having multiple areas with similar monster level but different weaknesses would help).
Of course this the opinion of a single player, but I’d like to see what others think as well.
