Why put the aram key drop rate fix on PBE and not live?

they're still messing around with code for something that only recently came out, they have to make sure that they test it somewhere that wont cause any damage first. you have access to everything in pbe so losing boxes or something else doesn't matter there since you have infinite rp/ip to use there. When you build something, you take measurements first and make blueprints, you don't immediately start cutting material and then trying to make heads and tails of it later.

It was in the announcement that it was coming live in the next patch.

They have to test their fix. PBE is for testing things. Soooo.....they're testing it on the PBE before they release it to live?

I mean with new stuff like this their fix could do something crazy like...remove people's boxes they already won/paid for. They can't just throw that shit out there and hope it all works fine. Could cause terrible results to customers.
