Okay lets stay a little focused on the "comp for 10m"-part. To be fair here, I'm hit by those changes losing out not only on the possiblity to grind via dittos but also due to the lost value on my PZ, so don't expect objectivity here.
If we are honest those 10m comps weren't for the purpose of having a noticable edge in pvp. Sure it can matter (I'm a 5x31 OCD-guy myself, lol), yet that was not the point of spending those 10m on perfect comps, it was the collection-value. As much as ppl love shinies, some ppl love perfect neutral-comps, may it be OCD-induced or just because they were rare af. Taking this perspective the change did not really implement a healthier pvping concering those comps, but simple killed a collectionbusiness almost totally.
I, from now on, can just hope that they don't implement something to kill male-only breeding as well so my Tauros stays kinda unique.
