Did they nef the repeateble Persimmon chest?

    I mean, in Conquest the last chest (Bizantium) always rewarded with 20 raw gold coins, in 3 v 3 with 15 gc, and in 2 v 2 10 gc, but now I find that in the repeats of the 2 v 2 season I'm only getting 5 gold coins?  Was always this way or did they just stealth nerfed it?

I think conquest the repeatable chest is bisanthium, which rewards 20g, mini season has always been this way
