Level Sync QoL: Keep Abilities Intact

[Felis]

-lower synced abilites' potencies
-lower synced abilities' enmity modifier
-further lower the stats of synced gear
-buffs for non synced players when in a party with synced players (determination/enmity/etc buffs)

You forgot "lower buff timers" and "lower buff effects"

The skills already are based off proper potency, no need to lower them because your weapon already gets lowered.

This only count for dmg skills and heal skills. How would you scale down something like Swiftcast (THM) or Leeches (SCH)?
