Was comparing the proc of 2 trinkets.
my thought process was such.
mirror gives 1926 master for 20 seconds, with a 10% proc rate and 90 sec ICD. with AB taking 1.73 seconds to cast, and needing on average, 10 casts to proc the trinket, it would take 17 seconds to proc.
so, with 20 seconds of uptime, and 87 (70 remainder of ICD + 17sec of casting) of downtime, I get 18.6% (20/(87+20))overall uptime of the buff, which I then multiplied by the flat mastery amount to adjust the values.
Any logical flaws I'm missing?
