Gen 2 is working and functional and should be the default. There are workarounds and you can get everything you need to play GSC. If PS is the official simulator and emulates the gens properly we shouldn't be told that the default simulator for the tournament is a second party sim. I don't have PO anymore, because PS is the standard, and I shouldn't be forced to use PO because my opponent wants to
The fact of the matter is we're still finding bugs in GSC on PS, which combined with its difficult recent history of incorrect Leftovers implementation and now rampant moveset illegalities led me to err on the side of caution and recommend that PO be the default for GSC in this tournament, as it's been proven to have correct mechanics for years now.
This is not at all ideal, as I too would prefer PS be the default for all gens. Hopefully, if in the next month we reach a point to where I can give the green light (as in we stop finding bugs), I will make PS the default for GSC and therefore PS the default for all gens and finally put PO to bed. You and others can even help in this aspect by playing a bunch of GSC matches on PS using typically buggy moves like Substitute and trying to find new bugs.
However, in order to finally leave PO behind once and for all this would also require us having correct RBY mechanics as well, and I was under the impression going into Round 1 that they were on PS but they are not (the whole status to stat modifier Speed mechanic is not implemented currently on PS, or it was not at least as of yesterday). This will probably lead me to make PO the default of RBY as well as I would rather we play with what's the most up-to-date if possible.
We use what's most readily available to us at the highest competitive level. We had to use PO for Smogon Tour when we still had ADV in the tournament despite PS being our official sim at the time because ADV was not completely implemented on PS. The situation has changed significantly since then, but it's undeniable that PO has GSC and RBY better implemented at this point in time. Hopefully, that is not the case in the coming weeks and we can switch to PS being the default.
