I would rather see the exp tables changed per guild. Or maybe certain guilds would get a negative modifier. As an example, a fighter killing stuff or a tinker forgeing/runeing stuff is based off of the skill %. It takes a lot more levels to perfect any skill the thief,fighter, or tinker guild has.

Where as almost every 5% skill in any magic skill..magery,enchantement, and so forth gives you more power and costs a lot less to get it from *1 to *6 and you get damn good exp for the spells.

This would be a good reason to have either multiple exp charts or exp mod per class.
