that would be a bad idea imo. after GM 137, I made a very realistic prediction/ guide/suggestion to Crate to smooth out the gm’s and make fans happy. 
all those in red were created and revelead already! ok I did not expect another monster reveal so there is that. and ok I admit 2 masteries may be too much but at that time there was not much hint to the paladin wannabe mastery. Now that shield mastery is hinted, they can now stick to just one and 100% fans like me will be happy!
