Well I got lucky and Yveltal shined 3 times over 3 days and 3rd was Modest! Very pleased that this didn't go to be a Latias luck level. I can't post photos through my phone atm so might do it later.

As MHWorld beta starts tomorrow I'll start a MM hunt for Own tempo Rockruff.
I just passed 3,000 REs at the trainer school. Stubborn shinies are stubborn.
In Sun, I have 90 eggs hatched for the shiny smeargle I will be using to hunt legendaries and EBs once I get the thing, train it, level it, and send it to US. I also caught a HA paras with which to breed a better one, preferably with Damp, so I can hunt blacephalon without having to worry about it blowing itself up. I have a male dive ball rockruff, jolly nature and 5IVs, ready to breed with the Own Tempo rockruff in order to get Own Tempo onto a rockruff that isn't in a standard ball.
Balls modify capture rates under specific circumstances. The only reasons one might want a Pokemon in a certain ball is (1) indeed for aesthetics, or (2) the different animations that accompany them.Outside of a luxury ball, none. It's for aesthetics.
Unless a luxury ball only boosts friendship at the time of capture? Then there is no benefit other than the ball looking nice.
