Support Skills don't have very high mastery levels. For dmg dealing skills it can strongly vary. A lot of them can go very high. I would just recommend level them as high as you feel like. Besides lower coodowns and higher dmg, the mastery isn't changing anything else. It's just a extra way to increase utility and dmg.
Because it was meant as a special skill that any form can use from the very beginning. Theoretical I could have used any other type of small critter instead of bees, I just found it fitting and bees are adorable. Bee already has its own complete skill set. It would extremely unfair if only the bee form could use it.
With 400 to 500 reputation you are on a good way for having acces to most of the guild quests that have no special requirement. Just make sure to check the left walls of the counter in the guild as well. Some quest also got posted there.
No worries, it's not like that I would be forced to impement any suggested ever made by anyone. Even less for a game that is already finished. I always only pick things which also sounds interesssting or fitting in. So no worries! I also take break months every now and then. The next one will most likley be November where I taking a break from developing^^
Fluffy stuff is what I draw most^^
