To be fair, he is right in that the rules clearly state that you aren't meant to use hacked Pokémon, even "legal" hacks. I agree with him on that. I'm not going to go mental about it though, I just wish TPCi would make their mind up; either remove the rule or actually enforce it...especially now money is involved, they need to deal with hacking.
But, you all know my stance on hacking
We're already seeing less people.
Attendance at UK Nationals was down over 100 on last year.
Attendance at DE Nationals was down around 150 on last year.
US Regionals are also having some low turnouts.
This year's format has kind of put the growth of VGC backwards, which sucks.
Next year should be good though, I know many people who chose not to this year but intend to next year.
VGC14 was a very fun format. I had some great creations out of that. VGC15 even allowed for a lot of creativity, even at high level. CHALK was a pain, sure, but not unbeatable. It didn't control the meta like Primals do in VGC16
