To me, the problem is obvious: they have abandoned their trademark style. Of course, we all love anal, but the fact is that tons of studios produce anal scenes, so if you want to be successful, you have to find a niche that allows you to stand out from the crowd. In the past, the thing that made Sineplex/LP stand out was the commitment to combining hard anal action with nasty oral action (like ATM, ATOGM, asslicking, piss, and cream). If you look back on all the "golden ages" (from the Jay Sin era, to the Evilutionplex era, to the "paradise" of late 2014 and early 2015), that's the one thing they have all had in common: hard anal mixed with nasty oral.
But for the last couple of months (from around the time of the piss ban announcement), it seems as if the nasty oral action has been almost forgotten about. This is why, for many of us, the scenes feel boring. If you're going to take the piss away, at least replace it with other types of oral perversions: more ATM, more ATOGM, more asslicking, etc. Instead, it seems there has been less of these things. That's why the scenes feel boring, and no amount of circus penetrations (like TAP) can make up for that.
I want to see how many people agree with me.
