I think that character portability needs to remain a pillar of the AL ruleset, regardless of the setting. Remember that at the very core of the AL, it's still based on a set of houserules. We're simply playing by WotC houserules. Our ruleset simply needs to work for our style of play.
I think that one assumption that everyone seems to get wrong is the notion that the default 5e campaign setting is the Forgotten Realms. If you read between the lines of all published materials, you'll see that the true default campaign setting is the Multiverse itself. We've simply only seen adventures that take place in Faerun. Why else would books like the PHB and SCAG contain passages about adapting material to other settings, even though no official 5e products take place in said settings?
I have a hunch that the grand plan for 5e is similar to the world-building done in the Marvel Cinematic Universe. Everything is connected. We simply haven't seen it all unfold around us yet.
As for what I would like to see change, that's simple. Since the current rate of Expeditions production is forcing older content to be replayed to accommodate more tiers with the same amount of Expeditions per season, perhaps that should be a priority target for change. I've personally reached the point where I have to remember which PCs of my long-standing players have already done which older adventures when scheduling games to accommodate my newer players because I've run out of new T1 material to run. Scheduling and prepping Expeditions was far easier in S1 & S2 because the playing field was more even. As the amount of tiers supported by Expeditions grows, so too must the overall number of Expeditions.
I fear that when T4 Expeditions become a reality, we're going to end up with a season with no more than 4 Expeditions for a given tier over the 5-7 months of play. At such a point, I wouldn't be surprised to see both player and DM burnout reach critical mass. There needs to be at least 4 hours of T1 material released each month to account for the new players who just discovered AL that month. This season has been the worst one for me to run from an organizer perspective. The person who's suffered the most madness this season out of everyone at my FLGS is me. Not one of my characters, but me as a person. The only reason that I keep running AL is that I enjoy the community that I've brought together at my FLGS. If it wasn't for them, I would've immediately quit running games when I first saw how big of a cluster




this season's schedule was.
