I am pooling more and more insanity as I get higher in lvl and I have chosen the Damnation talent.
I also use the PvP talent lasting plague, should I just be applying DP as soon as it is ready regardless as to whether it is on the target or not? Feels bad having full insanity and waiting for my DP to run off the target before dumping another.
A new DP does prolong the previous one, but i feel like there is still some sort of limit. For example if I use 2 DPs in 2 globals, It doesnt add twice full duration (6+6 sec), but it does like 8s or something. No idea if its a bug, intended or just a visual issue.
It simply adds your remaining DP damage into the new DP.
So if your DP does 1000 damage, and it has ticked for 400 already, it has 600 remaining.
Reapplying DP now will make the new dot tick for 1600 damage over the duration.
This. Theres no explicit “Cap” either to the amount it can stack to, just a realistic expectation you’ll reach a point where there is more damage leaving the plague each tick than you’re adding by re casting it.
