Sure, back in the old days we can just refresh it whenever and keep it uberbuffed.
But with pandemic, maybe they are changing the way it calculates.
Say you cast a corruption without any proc
18sec,
at 9sec, you refresh it when a uberbuffed corruption
now it's at 27sec, however not the entire damage is uberbuffed. The game takes 9sec of unbuff damage, 18 sec of buff damgae and divide it over 27 seconds.
So the extra damage corruption gained from the proc is still the same as the extra damage it gains from a normal 18sec uberbuffed corruption.
But keep refreshing your corruption will slowly balance this.
First, as we know the maximum duration is 50% of base duration, this mean there could be 2 way the system calculate the new damage when you spam corruption.
It can take whatever time left on the current corruption, and apply MIN(corruption duration{18second}, 1.5*corruption duration-current time left{so 27-time left})
Or it can simply use the full 18 second of the new corruption, and take whatever is left on that duration that can fit into the 27 second.
For example
you have a 27second corruption that is only using the buff to 66% efficiency.
It goes to 18 second, you refresh it with another corruption that still have the same buff on it.
Using the first assumption. Now you have 18second of 66% efficiency and 9second of 100% efficiency, this create a 27 second corruption at 77.3% efficiency.
If we use the second assumption, then we have 18 second of 100% efficiency and 9 second of 66%, which makes this 88.7% at 27 seconds.
Considering the someone above is saying you need to spam 5 or 6 corruption to make this reach full potential, I'd assume the first assumption is correct.
So if my hypothesis is true, I guess it's pretty safe to say while under proc/CD, we should not be refreshing the dot until it's absolutely less than 50% of base duration.
However, it should not matter if we fresh at 49% base duration or 0.01% base duration, as it's always giving the same amount of extra damage/GCD (18sec of buffed corruption,etc)
