The queue issue is on gaijin side, not consumer side.
They made GSB use “rotating line-ups” that are not actually carefully curated.
Meaning, despite the seeming promise that these rotating lineups would provide authentic-feeling match-ups and minimize IFF issues, in reality you still get tons of italian shermans, german KVs and so forth causing excessive confusion on the markerless battlefield and constant friendly fire.
Additionally, after failing at providing the promised outcome (authentic experience, sensible visual IFF) they still heavily restrict gameplay. If I wanted to progress tanks entirely using GSB, I’d be able to only play one or two days per week if not less because the tanks I have unlocked are only available every N days (WTLineup example: M4 Sherman:

If I only owned the M4 sherman and only tanks in the 2_1 and 3_1 brackets, I wouldn’t be able to play warthunder AT ALL today as today is 5_1 and 8_2_2, tomorrow is 4_1 and 9_2.
Therefore, queue times are sabotaged despite want and interest.
I want to play GSB.
I am not allowed to.
Whereas in ASB If I want to fly my 109 F-4 I can do it 24 hours of the day 7 days of the week. Now, some days I’ll have uptiers, other days I’ll have downtiers and that might affect my enjoyment (4.0 109 F-4 vs 5.0 Spitfire Lf Mk IX is not fun - it climbs better, accelerates better, turns better and is faster in the domains where it’s relevant. Only in stability & ease of use is the 109 F-4 better (lower skillfloor to not kill yourself from spinning out)) but it doesn’t prevent me outright.)
You can take live realistic scenarios and narrow them down to specific pivotal moments.
KRABB_NATION and WingalingDragon and InvaderPork do just that.
Last year they ran a community event of the Normandy landings in SB controls with curated lineups that make sense for the scenario (both tank and aircraft) and it was very fun.
Last year they ran a community event of the Iwo Jima landings across multiple days with timeskips to the hot zones and it was incredibly fun as well.
They’re re-running the Iwo Jima landings soon too.
They’re also doing Ju 87 stuka and B-17 dynamic campaigns based on authentic or historical scenarios.
Also there exists Il2:GB Combat Box that again uses the same philosophy:
Example -
Crossing the Rhine
March 1945 - Allied forces are swarming across Europe, liberating territory from the Reich. After capturing the Seigfried Line the 9th Armored Division of the US Army unexpectedly captures the only remaining bridge across the Rhine. Ludendorff Bridge is wired with six thousand pounds of high explosive, but as the Germans try to demolish the bridge half the explosives fail to detonate, leaving the bridge intact. The GIs quickly take advantage of the situation, securing and repairing the bridge and building tactical pontoon bridges to support their operation. “Cross the Rhine with dry feet, courtesy 9th Armored Div” is proudly painted on a sign across the bridge, with hundreds of tanks and thousands of troops making the crossing safely. [Mustache guy. I dunno if forum censors his name so I’m being safe] orders all possible measures be taken to destroy the bridge, including the use of artillery, heavy bombers, V2 rockets and even underwater frogmen equipped with explosives.
Mission concept and design by Talon, implementation by Alonzo. Thanks to Haluter and Jonno for extensive testing.
This is a very fun scenario.
Player tanks are also a thing:
