Instead of a regular champion roadmap our next couple of blogs will be detailed dives into how the Fiddle and Voli VGUs are progression as followup to the recent VGU voting. Will be a while until the next standard roadmap as a result. First Voli/Fiddle update should be pretty soon though.
Current plan is any champ or VGU that's in the game by 9.17 at the latest will be playable at Worlds. If Panth's in 9.17 or before, he'd be eligible. Not gonna comment on when his VGU release is though, that you'll have to wait and see on!
I understand the frustration bugs create and how it's disappointing to not get responses about them. I apologize that I'm not answering those questions. I'm not the right person to handle specific bug responses at this point though, my day to day's just not involved in that part of the game dev workflow at all and I can't justify the time to go chasing individual bugs down. Feels bad having to say that, but hope it's a bit more helpful than silence.
It's not something we've got any plans for at present. For one thing the way our internal tools are set up means it'd be a really large job to get some form of them that could be player facing. Wouldn't rule out the possibility of it some day of course, never say never and all that, but think it's very unlikely for quite a while at least.
