I think on my first playthrough in ~2003, I had Water on strength, Demi on magic, and Curaga on HP from early disc 1 all the way into disc 2 (lol). For some reason I leveled up Squall, Rinoa and Irvine a lot after Selphie's little base mission (60+), got Pain & Flare, then figured out those were good for strength, magic, and status-defense. The end result was that those 3 characters got stuck way behind the others in base stats at the endgame, with Squall actually having a lower base strength than Zell and needing STR + 60% to reach 255 (I think he reached the 240s with just 40%). Although I did get 600 Triples between Cerberus and Odin, and figured out how good they were for magic/drawing stuff, for some reason I didn't get Tornados until disc 3 despite finding the desert well before then. End result: crap file, but at least I figured out which junctions were good for which stats before my second file.
