For me it's not that they're getting worse, just they're getting repetitive. I've been playing the things since the SNES days, and it just doesn't feel like the genre has come that far since then, unlike most other genres.
WRPG's for me have passed them nowadays, they just kept pushing the boundaries, going further, wanting to do more and more incredible things.... where JRPG's stalled or even went backwards lol.
Saying that, I've no idea where I want JRPG's to go... but I just want something to come along and be all different and awesome.
