That's a very good question.
I know anime takes advantage to showcase Hinata, which sadly connects to NH since at times it's confused with love and acknowledge, but they have been pushing NS sky rocket for a while. Heck, I wonder who's pushing it worse, Fairy Tail or Naruto. Anyway, back to this. It's really hard to say but I do think it will be much less than now.
In the anime, everyone got a head start with Hinata in episode 1. Granted Sakura appeared in episode 1 too but the problem is that because Hinata appearing earlier, people mistakes episode 3 to be love center episode, since it's dealing with Team 7 center. That said people think they are dealing with romance anime like stuff they get in Toonami/adult swim. Therefore, they assumed that Kishi would go complex on romance, which in reality it's only in Team 7 and Sasuke pretty much say "kitten this." So have not been early appearances, I think the fans would be lower than now. In fact, I don't blame filler as in those filler episodes from filler of hell, rather blame the placement of the canon mix with filler to cause confusion.
In Shippuuden, they improved it much better, though there are some problems. That said if they kept it normal as manga, none of this outbreak war would have happen.
What pairings are FT pushing too far? I don't really care for any of them save for Gajeel x Levy
