Yes, ideally testing two Pokemon at once is not optimal as the focus of our voters put their attention onto one of the Pokemon and have the other be ignored. While generally this is true, a lot of the time we test multiple Pokemon at once for the sake of saving time or for their extreme similarities. In this case, Sableye and Shadow Tag were components that made some Stall teams seem too strong or too good. Testing them together was seen as a non-issue and fact of the matter is the Council and the community saw them both as equal issues. Even if we wanted to test one at a time, how would we decide which should be the priority? These Pokemon were so closely intertwined alongside the fact both were seen as equal issues; what exactly should we have done? Arbitrarily tested one first when the other could have been the root of the issue or deem the other one not to even be Suspect worthy is the only option we had aside from testing them both at once. Even if we decided on which should be tested first, this specific situation isn't remotely like testing Keldeo and Tornadus-T or even the first test in XY; these Pokemon were almost entirely seen on the same team, both restricted your ability to break certain teams, and both were equally important of our attention at the time.
I understand your point about wanting to progress the metagame as fast as possible and doing tests late may cause issues, but Sableye was never thought of as a immediate concern by some of us. Sure, some of us may be pro-ban now or were during the Suspect, but no one pushed for a test to happen because they didn't feel it was a pressing concern. Obviously no one needs to break their back over wanting a Suspect in the Council, but not once do I recall anyone asking about testing Sableye again and the only times non-Council members brought it up to me were the ever-so-random comments on PS such as "TDK ban Sableye already" and "TDK ban Sableye pls" which I generally ignored after the same people already asked a few times. The last time one of us brought up testing Mega Sableye in the Council channel was in April where everyone unanimously agreed to doing nothing with Mega Sableye in the immediate future.
I know what's expected from a Tier Leader and I know how to keep track of my metagame and its community. I can't speak for everyone in the Council; there have been periods of inactivity. Around the time I took leadership the channel somewhat died for a period of time until I brought up SM tiering, which we discussed a fair amount. With that said, we have most definitely not been inactive in the slightest in the past few months. To say that we're lazy, incompetent, or just don't care is not only insulting but an absurd comment to make when you simply aren't in the Council channel. I did not believe Mega Sableye needed one myself and still don't, but am perfectly alright with it getting tested as I can see why it's an issue and why people believe it should be tested.
Also general thing: just because it's late in the generation does not mean something is immune to be tested; if it is test worthy, it will be tested. I would much rather finish up this generation with the best metagame possible, albeit quite late, than to have something that needs to be fixed down the road by a PR thread similar to Baton Pass in Old Gens and Sand Veil. If someone, whether an offhand comment from someone, from a Council member, or from myself, told you Sableye was not going to get tested they either; 1) assumed something they don't know, 2) were wrong, 3) weren't clear or said something to be left alone. If there is something you should be brought up, I don't care what people say; feel free to bring it up again. I don't mind taking PMs about potential Suspects if someone is unsure on if they should bother posting about it elsewhere. I would much rather have something the people think is potentially too strong be brought to my attention than for it to be ignored. This is not to say I need people doing my job for me; I am perfectly capable of keeping up with the metagame and knowing what I think of every Pokemon, but knowing the public opinion on certain Pokemon is always nice to know.
PDC already covered everything else I care to say.
