Love based? You mean the love arc?
Well I just mean in general. We have that Kagura one, which is funny yet cringeworthy because of that boy, we have what you said, though that was supposed to be next, and so on. What I meant is not entirely based on romance/love, but it has somewhat involve with it. Still waiting for that Ramen Arc dammit.
i'm afraid of bad animation like sakamoto's recent episodes.. i'm a big fan of the shinsengumi (and gintama in general) but i can't help but feel that the studio is a bit bias.. what with the difference in budgets...
Well, it's a bit early to call but this series is going to need to save money for that arc and really, it's crucially necessary. This is "You mess it up and I'm done with anime" arc. Much like with Naruto fans with Pain Arc and boy, does it show. That arc needs full blown movie treatment. So it could be a coincidence or it is what you say. Again, I like to think it's saving budget for that arc.
