SO you would waste the exp from a level 6 preciseness to put into a blue morale rune. yeah lets go make this feature now devs. - NOT I think you need to get further into the game to understand how bad an idea doing that would be
And I am not a VIP6. I have no idea where you got that from.

I am a vip4

have never bought a coin chest.
I get all my gold from playing the game. I will occasionally buy gold form shrine and fair. But I earned most of the gold I spent in the temple. And have worked my but off to get the runes I have.

Stop asking for a pretty much bad idea of a feature and learn to play the game, and stop putting down coiners who, without them there would be no FREE to Play games to play.
