I just read the news for tomorrow and these lines intrigued me.

Adjust Unit Balance
- Adjust Unit's Parameter
- Adjust Skill and Ability
- Add Unawakened Ability to Some black rarity

Any veterans have any idea what these may be? Especially the ones who play the DMM version.
I'm hoping for silver abilities(level 55) and the buffs to current classes(e.g. archer damage bonus vs. flying)
Slightly unrelated, I hope Bernice or Gellius pops up in summon chance up as well.
