The crux of the issue op presented is either the rewards should be increased to remain relevant, or iLv sync should be removed/toned down. If the idea is keeping the dungeons as """""""""""""""challenging"""""""""""""""""" as they were at release then the rewards they give should be proportionate to what they were at release. Instead we end up with dungeons that give practically no reward for all the effort they take (Neverreap).

Basically the effort needs to be equal to the reward and if they're not going to increase relative reward they need to at least remove iLv syncing.

Not to mention iLv sync nulls materia which nulls hundreds of stats...

That said, it'd be neat if we could set iLv going in, and increase the reward the lower we set it, with min iLv being the option for the greatest rewards.
