The idea is, Fast Cast affects casting time of a spell. If you want to shorten the duration of the cast (like having it go off at 60% into the casting bar instead of 80%), put gear with Fast Cast on at the start of the spell. Homam legs have the Fast Cast trait on them, so they will affect casting time.
Fast Cast and Haste affect Recast of a spell. If you want to have the recast timer of the spell be 40 seconds instead of 45, have Fast Cast gear and gear with Haste on it equipped at that point in the casting bar when the spell actually goes off. Homam legs have Fast Cast and Haste, so they will doubly affect recast time.
You can find every spells' base cast time on wiki. You can set up macros with a wait in them in either FFXI macros or windower macros, hvae spellcast do it for you, or even manually swap with a separate macro, or a built in <stpc> command that fires off the gear swap when you hit enter midcast.
BG elitists <3 haste.
Allatards/uber casuals hate elitists.
Allatards/uber casuals hate haste, as valuing it would acknowledge that elitists are right
People don't hate emo kids because they're "misunderstood." People hate emo kids because they're useless.
