Really? Jenova with 200,000 HP (where a properly suited character with dual synergy can maybe do 2500-3500 per attack) that can one/two-shot kill Level 50+ characters and gets two attacks per turn is where you think the difficulty should be?
Jenova is not going to 1 or 2-shot with Protectga and Power Break up. I did a 2nd time through the last elite just to prove a point - It's definitely still a slog and the fight ended with 1 action star, but properly spacing out the 4 Protectgas and 8 Power Breaks with Lenna healing (nonstop mass-regen from the soul break) I was never really in danger of dying except on a double Gas - Gas is the most damaging by far, even with Magic Break, which sucks. Double Laser hits for ~600-700 tops with Power Break and Protectga.
Don't get me wrong, it still is a slog, and the trash is absurd because it pretty much requires you to use Retaliate to save ability counts for the boss, but if anything it's a testament to bad mechanics rather than bad balance.
Bad mechanics in that:
- Power/Magic break are too essential because it cuts damage by about half
- Protect (or similar SB) are too essential because it cuts damage by about half again
- Ignoring VIT0, Retaliate is still too strong a mechanic if you have one weapon that outclasses the rest for a specific realm
They kind of solved the first bullet point by giving bosses Break resists (so that tuning doesn't have to be done with the assumption that everyone's gonna be able to cut incoming damage that much) but I'm not too sure how they can gimp protect or the other absurd soul breaks like Lunatic High without essentially forgoing 'being true to the franchise' since shell and protect are pretty absurd throughout the franchise. The third bullet point eventually sorts itself out the longer the game exists, as your 2nd and 3rd melee weapon approaches the power of the first, because in terms of hard number crunching, if you have 3 equal weapons, the opportunity cost of Retaliate (using up 2 actions for Boost and Retaliate every few turns) gets outweighed by everyone hitting for a multiplier with abilities, compared to hitting for the Retaliate guy's normal attack value x2 (with double cut)
That being said, I do think 200,000 HP is a little overkill even for an endurance/turtling test, and the fight would have benefited a shit ton from boss HP bars considering the need to ration mitigation abilities properly. (e.g. casting Protectga every 20% hp and Power Break every ~10% HP according to boss HP bar would make it much more straightforward than constantly playing mental Tetris and remembering how many turns it was since the last cast)
It's hard, but it's nowhere near the level of bullshit that was Sorceress elite, or even Red Dragon.
