i dont see how making it a trait is any different from the current one. trait is just a skill that is always active 24/7 and greased lightning is a skill that need to be in constant activation in combat so... yeah.

my take for the GL move into a trait could mean that we might have a new mechanic system to replace the GL.

either GL trait will become permanent but with reduce effect or the timer is still there but will become much easier to maintain

and yeah for the love of god they better do something with tornado kick lol
