level scaling enemies

[TheSpoonyBard]

It also gave the extra bosses (omega and ultima weapons) a boost, and it made the last boss actually make you take more than 1-2 turns to beat the game (w00t!).

Ultima's level scaled, yes, but Omega is always Lv100 unless you're playing the PC version. Ultimecia's level is capped at 65 so it is quite possible to be overpowered for her.

And the fact that the level scaling works on a discreet system (to my understanding things only change at level 10, 20 and 30) etc rather than continuous is what pissed me off the most.

Enemies' level are either 4/5 or 6/5 of the average level of your current party.
