Hello!
While playing, i remembered a reward from quests on an old game I played: Experience cards.
Due to the multi-classes of the game, it would be very helpful, specially for leveling side-classes if quests and levemets rewarded players with untradable experience cards.
One of the biggest hassles is just how boring it is to level additional roles to a character. With this, we would be able to farm experience from your main class to your seconds. It would encourage people to level less-played classes, like healers and tanks.
It would be great if we had 2-3 categories of experience cards:
War and Magic, Hand & Land.
Quests and leves related to each category would reward their specific experience cards.
In my old game, experience cards were also level-ranged. So some cards, per example would give 200 exp points and only be usable for above-level-10 characters/classes. 5000 exp points, only for above-level-30 and so on. This would keep a person from insta-levelling a class.
