A bit of backstory: I've been playing GW2 since beta and GW1 before that, so I am familiar with the game mechanics.
Now, I have beaten Moth breath 3 times Solo.
Once on my Engineer, my Necro (reaper elite) and on my Revenant (renegade elite using Scorchrazer/stonehammer). I won't say it was easy and I had to do the fight a couple times each but I won.
However, when I go to help my wife we've had to wipe a number of times (far more then I had to alone) and I'm at a loss as to why. Seems to me that, if anything, the fight should be easier with 2 people.
We also adjusted her Guardian using a Power DPS build.
She does as I instruct and lets me handle the blight clones while she tags them and/or Moth Brain and waits for the rifts to open. But no matter what we do, we cannot bring it down.
So what I'm curious to know is if ol' Mordy scales in strength based on the number of players arrayed against him.
Any insight is welcome.
