Transpose I use for any FATE that removes Blizzard III, or I Fire I too much and need to Transpose for MP. Surecast seems almost useless as it doesn't surepass even Paralyze, though, against Frogs, I can see a use. Freeze I have recently found useful in some of the FATEs in Coerthas, the Ice Sprites in particular, or whatever they're called (name escapes me for the time being). Being a Ranged, MP inducing AoE, it has minimal use as Blizzard II works better, hits harder and faster. Lethargy I can see some use for, say... High end dungeons? But essentially, have a lancer and cast Blizzard 1, has probably a better effect. Transpose really comes into it's own after using Flare, as Flare uses all your MP and gives you the Astral Fire III Buff.
