Encounter Design

[Garlyle]

The deal with customization is that in order to provide a well-tuned challenge to players (and not ones that can be instantly reduced to ezmodo), you have to in turn assume they are going to be as well prepared as possible for it - whether that's in the form of elemental resistances, skills they've learned, etc. ; which then creates a problem that either you get excluded because you don't have it(*)... or you do have it, because you spent time grinding out the stuff specifically for this content, and the time for this other content, and the time for this other...

(*) See what happens to WAR that don't have Provoke trying to enter EX Primals or later Coils - and that's with the minimum we currently have.

It's not inherently a bad thing - but it does come with its downsides, and those are things Yoshi P's said he's deliberately trying to avoid.

(By and large by the way, Dark Aeons are not what I'd consider good encounter design in FF. They are by and large just raw stat/grinding checks. Ironically, the rest of FFX is actually pretty fantastic about that.)
