There's no point in doing a placeholder when most people won't look back at it, and especially when it doesn't get done in a timely manner
In lack of that, your post looks somewhat hypocritical.
Despite losing two resistances, I think Genesect specifically in Reborn has gotten stronger with 6th gen because of the weather change. Previously we had an over-abundance of weather teams which would almost be guaranteed to run swift swim/sand stream/chlorophyll sweepers that had no problem out-speeding and striking down a typical Genescarf set. Since we no longer have that constant overflow of speed it's much easier now than it was last gen for Genesect to find room to get its momentum going.
This is the main reason that my stance on Genesect has changed. Previously I defended it staying in OU but in this meta, I do believe it's problematic.
Incidentally, now that I think about it, I can pretty much say the exact same thing about Blaziken. So although I would typically want to keep Reborn's options more available than Smogon's, I think perhaps we do need to consider Blaziken as well.
However, since this is a point of contention, I suggest we move forward with these changes, sans Genesect for now, and spend more time deciding what to do with Blaziken and Gensect. This way we can at least get some tiers going.
