How would you go about remaking Ruby/Sapphire/Emerald

The point I'm trying to make, which nobody has yet to refute, is that XY OU has much less team variety than BW2.

Give people time to experiment. There are new toys to play with that people are overusing, it's to be expected.

Also, there is a big difference between being in OU and being something that every single team needs to have a solution for. Reuniclus was OU but did in no way have as much usage nor did Reuniclus define BW OU the way a weather inducer like politoed did.

I am currently having far more fun in XY than in BW OU, if that's because i'm blinded by new toys and it will eventually become boring, i don't know. But for now i am quite happy. And i don't see myself getting bored of XY.
Not to mention tyranitar is still one of the most used mons in XY, so is excadrill.
