All the posts of "how is Cyan useless?" makes me wonder how many people know how Sabin's blitzes work (they're magic ... well, Pummel and Suplex aren't but the rest are). Though, useless may be pushing it (more like "average" if anything). Cyan lacks anything special going for him besides Tempest; Dispatch is cute but it doesn't scale with weapons so it tapers off in usefulness. He's not a terrible physical attacker but just not as good as almost everyone else due to equipment (i.e., nothing comparable to Valiant Knife, Illumina, Dragoon setups, etc.). Him and Sabin are basically just end-game average, though Sabin at least brings Bum Rush.
That said, I'd love for a harder version of FFVI so any of the above actually matters. Also, maybe some more depth to the WoR could've been useful. I actually liked Tower of Fanatics/Fanatics Tower, though it's not that hard of a dungeon if you're prepped right (Wall Rings and Float basically trolls the place if I recall) and really would have liked for more places like that.
