To be fair, ORAS has enough lazy moments as well, especially when it comes to aesthetics and level design. For example, while X and Y had the Kalos symbol for Pokemon obtained in Kalos, ORAS uses the same ugly Poke Ball sprite that's probably only meant for Pokemon transferred from older gens. Also a lot of caves and routes just look like they were compied from the original games, only with the graphics being updated. Then there's Flash which got it's old mechanic back and that it is (somewhat) neccessary in order to traverse Victory Road, as the inner part is really dark.
I'm also a fan of the mechanic in X and Y where they put trainers in front of a mirror and they were still able to spot you.
