As a thief, I agree with Rancid. DoD really isn't haste. Ideally, thieves need a top to bottom overhaul... A lot of people say they are OP because poison lore gives ridiculous amounts of xp (steal pick pocket and pick locks all suck ass now...). but they don't realize, I'm at almost 50S and still don't have all the major thief skills at a decent level...

That aside.

F being creative. Keep your job simple and give the other classes haste. They'll still get crap for C devs anyway, so it's not like haste will suddenly and majorly unbalance combat since they'll have to work twice as hard to get the same skill levels.
