Improvements to Cast Mechanic
As it is, the Cast mechanic showCastBar is not very customizable, and has a preset "Progress" bar and text which can't be changed or removed. I suggest that this should be modifiable through either a parameter or in the MM config.
It also does not show the casting bar above the heads of players, only mobs.
The skillName parameter does not support placeholders, making it difficult to create a dynamic casting system or show the time in seconds before cast.
These issues being fixed would make the cast mechanic much more useful.
EDIT: It doesn't seem like any of the CastBar config options in mobs-config work? Tried changing offsets and billboarding, nothing changed in game...
