Quest rewards

Most rewards take the type of items, cash and reputation, but some quests (especially class-specific ones) give abilities or spells. Some of the more desirable reward items consist of uncommon high quality or much better products or recipes for use with professions. All quests tend to include XP as a part of the reward, even though some repeatable reputation quests don't reward XP.

Additional notes:

Many quests allow you to select amongst reward items wow fishing gear.

Most reward products will probably be bind on pickup, also known as Soulbound.

The completion of quests will also impact your reputation with specific factions, which can have additional advantageous effects like less expensive prices at vendors and access to special vendors such as mounts wow fishing mount.

Some reward items may not be usable by your character (usually according to class).

Level 60 (non-expansion owners), level 70 (TBC expansion owners) or Level 80 (WotLK expansion owners) characters now gain cash rather of XP for turning in quests. This was done to encourage them to continue completing quests within the endgame.
