I'm with Shihnes this time. Every single monster is unique and Capcom does a great job avoiding ditto movesets in the most recent games. That's saying, even Diablos species and Monoblos Species feel different in 4U now so fighting each monster is supposed to be posing a different challenge no matter how close their movesets are to another.

Telling that a monster isn't worth bringing back is like thinking in one's own interest. It's good if you are a veteran to the series, but you should acknowledge that there are still many players that debuted with 3, 4U or will with X, and never fought a Ceanataur or a Lunastra.

On the other hand, some veteran players might be happy to see again a monster that they missed. Not that some of them ranted about... Not seeing Lunastra back when Teo was announced for 4. They were the same all together.

To me nostalgia is good enough a reason to bring back a monster. No need to greatly alter his former moveset, just look at Narga.
