Un-gimping magic procs in dynamis

[Yinnyth]

While I largely agree with your argument, your numbers here don't add up. Threnodies have a 2 second cast time, so with 50% spell cast time reduction it would be 1 second each.

I did not math out the fact that I could do 12 threnodies in a minute. I went outside Jeuno, stood next to a lizard, set a digital timer to 1 minute, then started spamming threnodies as fast as I could until the timer went off. I got 12.

You're under-estimating the delay after the spell casts. Just because a spell has 2 seconds casting time, and I have song cast -50% doesn't mean I can get 60 casts per minute. I can't even get 30.
