I'd like to suggest that with the new level cap you find a way to increase the Firewind and Earthsea forms to become level 2 say at level 140?
This would increase the amount of time you can be in form to become an hour as the current time is only 30 minutes.
These skills were free to begin with and i'd list to suggest it to cost 3k SP for the 2nd levels as SP becomes very easy to come by after level 140 and if someone truly wants a longer form they would gladly be willing to spend the sp to acquire it.
Most potions last for an hour while some last for 3 hours. I do not see any harm in making this change.
