To be fair the teasers haven't really been interesting for a while, unless they go an do a unique rework or some such and start posting a lot of actually new stuff. Most leagues it's like "look at this new div card, it gives you a very rare item with guaranteed double corruption and will likely drop at a horrible rate as a result and few ppl will ever see one" and some "here's some free qol change for something you've only been asking for 7 years but due to clunky original code it took us until we decided to fix it in poe2 to figure out" kind of thing. Like you can split currency with the trade open next league I saw, you'd think maybe that should have been added at some point before.
They just reveal the new league stuff all at once nowadays so makes sense the teasers aren't really interesting or worth getting excited for unless they do a big rework(like unique rework or ascendency rework and such).
