I would recomened to improve buffs for c7 bosses. 

20% drop rate is realy nice reward, but +1 ap/dp  is a meme.  It is like, we didnt know  what  to add, so lets +1 ap/dp, pog. 

My suggestion: Reward for Earth - 20% drop rate,  for Sun - 15%, for Moon - 10%.  It would also be great if these buffs would stack with each other

It would make no sense to have different amount of droprates for the different boss types.

But yeah the 1AP and DP is totally useless, but it atleast clearly show how clueless the devs are about their own game. They literately doesn't understand how much the stats worth.

They should simplify it to if any of the c7 bosses killed you get 20% drop and that's all. Or 10% for each boss kill if you want it to stack. Altrough it's a pointless feature on a dead content so it doesn't matter. They should not waste developer time on this when the balance is in worse state it ever was...

You guys don't get it, the 1 AP/DP is a bracket jump and at ~740+ its priceless, so now you can see what would it be worth = its will worth nothing, nothing going to change if you hit that bracket, so instead  try hard and suffer, just play FOTM class and get more FPS.
