I know the official Freya notes are:
Pet / Servitor Changes: Any and all buffs applied to the summoner character will automatically be applied to their servitor pet.
I think changing it to having the pet/servitor inheriting all buffs cast on the summoner when the pet/servitor is summoned would be a positive addition to the server without breaking too far away from the official Freya ruleset.
As it stands, classes that rely on a pet like DA or PK are unable to use a mount or take the Gracia boat with their panther or phoenix summoned.
These classes rely on their respective pets to be competitive as they are a core component of that class. They either have to have buffers in Gracia (which can't be summoned back to the main world), or deal with the fact that they will be functionally impaired while in Gracia.
The mount system is also gamebreaking in that these classes need to either be summoned everywhere or they need to deal with the impairment of their servitor/pet.
