It's the dev's fault if they don't take into account overgearing though. Especially considering this game is heavily based on vertical progression.

The simplest albeit not necessarily the best solution to this would be enforcing ilv syncing on every fight to the highest ilv obtainable during the patch when they're current (e.g. 210 for thordan ex and gordias savage, 240 for sephirot/nidhogg ex and midas savage, etc.), though it seems like certain fights from 2.x still have problems with bad pushes even at the intended max ilv (?), can't say for sure since I started playing after 3.0.
