I would fully support making the crafting system worthwhile and a necessary part of the game as long as they made it so people who did not want to craft would not be forced to craft. Something that combat-only players could use to make money... for instance, the best crafting recipes would have materials that only drop in dungeons and endgame raids. Bosses would directly drop "good" loot, and give tokens for equally good loot as they do now, but they would also drop materials for crafting the "best" loot.
