Could you make it so that the transformation buff lasts an HOUR? Rather than only 10 minutes?
I know this is gonna come from a purely rp perspective but I can already tell its going to be rather tedious to have to cycle through sethrakk/k’thir models to get a specific one. The obvious answer is prisms but that is party dependant for the most part.
Extending the actual buff timer would REALLY help to mitigate that tediousness.
