I'm not sure if this game is going to only allow one job per character or be like ffxi where you can have any job on one character. But I would love to see 2hrs be done away with.
Most of them are never used in every day situations because no one knows if they will need it in the near future which almost never happens so they never get used.
An idea I have was to have racial ability's and they change depending on what job you have but keep there racial flavor. Like lets say a Hume's racial ability was to increase haste. If you were a mage it would decreases spell casting time to make you cast faster. or if your melee it would make you attack faster.
But my point is it shouldn't be 2hrs they should instead be made 25-30 mins tops that way more people would feel safe using there main ability without worry that right after they are done using it they will actually need it.
