Don't be rude when you're correcting someone.
Ardeaf, in your settings, change the maximum speed to cast AiS from 1.8 to 2.1, swap the AiS glyph for AS glyph, and RF glyph for CS glyph and you'll notice similar numbers to dropping AS entirely and glyphing appropriately. However since this spec has significantly better mobility it becomes better in a real world situation.
Your entire post is completely wrong. If the maximum speed to cast AiS is greater than my actual AiS cast without dynamic haste effects (2.0s), then I will always cast AiS. I went ahead and plugged in what you suggested and not surprisingly (with debug shot information enabled) I never casted AS and always hard casted AiS.
edit: I tried a bunch (about 4) different reforging schemes and a shot priority with casting CS on CD and using AS as a focus dump, and nothing comes close to hard-casting AiS (the closest I got was 300 DPS, which is with very low latency, and at a more realistic latency - 100ms or so - the gap increased even further).
Currently I do not see hardcasting AiS being beat by AS at all - even in real-world situations. Ideally you wouldn't have to move at all, but even on movement "intense" fights like Atramedes air phase the movement hardly impairs your casts if you switch between fox and hawk frequently enough.
