I'm sorry if this is glib, but I really can not think of anything other than, That sounds like a you problem.
There's clearly demand for longer abridged series going by SAOA's popularity, and frankly a core element and draw of SAO Abridged from the beginning was that it actually aimed to tell a story rather than just pack an incredibly brief runtime with as many jokes as possible. SAO Abridged has from the getgo packed plenty of storytelling and made a conscious effort to paper over the original work's plot holes and flaws in characterization. That necessitates time. If you want a series that just jokes packed a mile a minute in short chunks, then that's not a bad thing but it's also never been the type of Abridged series SAOA has been, and its not the type of series that won SAOA its popularity.
So, to reiterate, That sounds like a you problem.
