It's not even circumstances, Jellal and Erza met each other again. There are several instances where we deem it's reasonable enough for them to accumulate some moments from them that we may not have seen. For once, fight side to side with each other I'm not a fan of the ship, but Mashima simply has no excuse this time. It comes down to planning, and Mashima hasn't planned to give Jerza those moments simply because it's possible that he doesn't care much about the ship compared to the other big 3. So far the only moment we got from Jerza recently was in the omake, which was like in the end of it, and that was for a short time. Again, I'm not a fan of Jerza whatsoever, but facts are facts.
Jellal and Erza vs
this guy
^Yes, this badass looking guy right here. Not the new fail pretty boy design Mashima changed him to.
would've been much better than the atrocity we saw in the manga. Jerza moments would likely ensue.
I agree with Jellalsexual, Jerza isn't a side pairing, it's part of the main 4 (Erza is in it for god sakes) so it should get as much as favourable treatment as the other 3. Likeability of the ship itself is secondary. Equality is primary. As a writer and author of the manga, you need to be fair.
