Your assertion about the Base TH Rate X is correct. However, I keep explaining your misunderstanding and it's not getting through. We know the Base TH rate X decays, but we do not know if it is linear, constant or otherwise modifiable or preventable. (It was also suggested on FFXIAH that TH procs occur on the mainhand only, but may occur on offhand double attacks or offhand critical hits (either by accident/bug or on purpose)
