Well it's more that TriD is used inside Trance so there is a fresh set of Dots that have been buffed by the trance. Now if Contagion is blown before going into trance you no longer have the opportunity of extending a buffed set of dots. So effectively it's wasted.

Edit*
Just to add as Contagion has the exact same cooldown as TriD. So every time you go into Trance both TriD And Contagion should be used in conjunction with one another. They shouldn't really be used apart on a single target rotation. Obviously AOE Dps on trash would be different.


That said, Ace has somewhat fixed it as it doesn't seem to use contagion outside of Dread Trance,
 although it's not working perfectly still but I am wanting to do more testing before commenting on that.

2nd Edit*
My first thoughts on the current behaviour with contagion being used inside Trance is that it takes too long to be used after TriD So what is happening now is that We enter Trance TriD will go off but Contagion takes too long so their cooldown timers get further and further apart Eventually meaning that Contagion will not get used in one of the future Trances.
I see two possible solutions to this problem or a combination of the two.
1. Make Contagion go off faster once TriD has been used.
2. Make The bot Wait a little longer before using Trance when Contagion cooldown is still not ready.
