I can see where you think this might be useful and I'm certainly not level cap. However, I've been playing dot classes a very long time and enjoy it to say the least. This is something I do while fate grinding though everyone says I should just level glad to 4 and get flash and have fun. Anyway, the idea around the current optimal opener is that you're getting two festers out during Raging strikes. If you don't have that yet you just need to go archer it up till level 4.

You're effectively losing ticks dot ticks by clipping with ruin II. Dots are our primary and major source of damage. Your filler is just there to be your filler. When you compare its hits to your ticks you're not gaining any damage. Taking that a step further because of the way dots tick in this game not having them up as soon as possible hurts you. Someone could correct me if I'm wrong but the way I was explained how they tick in this game is not based completely by the time they are up.
