Last year's format did a lot right, with 8 teams and 10 slots, featuring LC, PU, NU, UU, 4ou (including a bo3), Ubers and DOU.
LC and PU were added, and both fielded competitive pools and had a generally solid public opinion. Talks of cutting them feel extremely arbitrary and silly.
8 teams was clearly fantastic, removing issues from the previous 6 team formats with the bye week, awkward main season and such.
My main agenda - expanding the format to 12 slots.
My proposed format:
Ubers
4OU
Bo3 OU
UU
RU
NU
PU
LC
Last (Sixth OU, ZU, DOU) in preference order.
RU has featured in tournament play throughout the year as
Amity mentioned, featuring RUGL, RUBD, RUWC. The playerbase is largely diverse from the rest of the ADV Lower Tiers community (meaning that it won't particularly thin the pools for the other tiers), and it has a lot of support from top players (even in this thread, Heysup and Fruhdazi both posting for its inclusion). If the primary criteria for being involved in this tournament is the tier being able to field a competitive playerbase, ADV RU has that in spades. It's proven to be competitive and healthy over the course of multiple tournaments recently. ADV RU Circuit playoffs are on right now even, putting some of the top competitors on full display. RU's inclusion in this tournament seems like a slam dunk.
Between the amount of strong and competent OU players on last year's benches, and the over 700 participant Revival tournament featured recently, coupled with ADV Seasonal having far and away the most signups compared to any other oldgen (over 250 compared to DPP and BW not cresting the 200 mark) the argument for OU slots to increase seems unassailable. In my eyes, the playerbase would be able to support 50 OU starters with ease (in a 6OU format with 8 teams we have 48), let alone the 40 that come with 5OU. Remaining at 4OU in this great expansive era of ADV seems extremely unrepresentative of the playerbase, and it wouldn't lower the quality of the tour much if at all, I believe, to expand the slots.
With RU's inclusion, and a fifth OU at minimum, we're left at eleven slots. Twelve, if you count doubles. However...
Doubles has its inherent issues in a predominantly singles team-tour. It's hard to prep it as a teammate or manager, hard to sub into the slot or flex into it, due to how esoteric it is when laid alongside singles tournaments. Doubles takes away from that part of the team-tour experience by sticking your doubles player (or players) on an island. This is compounded by the facts that:
There is minimal overlap of ADV DOU players playing other tiers.
There is a dearth of resources for the tier, raising the barrier of entry.
There are minimal tournaments for it compared to the other tiers - as
BIG WILL said, the tour scene is dead at the moment, the most recent notable tour ending six months ago.
As Colteor said, it's uncertain if there will be a competitive pool given it was sketch last year and enthusiasm seems low.
The explosion ban has radically shifted how the tier plays/functions - notably meaning that with a relatively dead recent tour scene, its an untested tier going into this tournament!
You're essentially gambling on your doubles player that they're gonna figure it out (as a teammate or as a manager) and there's not a lot you can do to help them. The issues with isolation that come with doubles being in genPLs is exacerbated by the esoteric nature of ADV DOU and the factors cited above.
If it's featured in this tournament, at least make it Bo3. The players were clamoring for it due to the volatility of the format and liking the consistency that comes with it, last year featured a fantastical amount of gentlemen's bo3s.
For these reasons, I would support primarily the format
Shitrock enjoyer mentioned of:
1x Ubers
5x OU
1x Bo3 OU
1x UU
1x RU
1x NU
1x PU
1x LC
TL;DR
LC and PU were great last year and should be competitive this year, keep them in.
Doubles had its issues and is looking like it will have them this year - please axe it or at least do bo3.
Expand to 12 slots - we have an enormous amount of competent players, especially in OU.
RU will not pull overly from the other pools, and features its own strong playerbase and is generally liked + has had a lot of tournaments, please add it.
Run a 12 slot format with at least 5OU (with one Bo3, that was great and well liked), featuring RU. In the last slot, there's argument for a sixth OU (fantastic but I understand there will be initial hesitance what with people suggesting that OU is stretched thin already, even if I disagree heavily), for ZU (there was a recent big money tournament, but the winners and top placers were predominantly tournament players and NOT ADV ZU players who signed for the money. Also, the recent drops featuring Mightyena have shifted the tier in a way that many are unhappy with.) and for DOU (if there does somehow look to be a very competitive pool, at least make it Bo3. Please don't keep it in for the sake of maintaining status quo in the face of fantastically better options, especially don't keep it in the format if we do not expand to twelve slots.)
Thank you for your time, let's have a great ADVPL this year. Super hype!
