Is my build viable for wvw/pve?
Have a look at this i used gw2buildcraft.com since i found it more accurate. I made 2 builds, one is with what you have given in your and link and one i think is bit more optimized with little changes. Also you should know that one weapon set cannot have 2 sigils that are the same, how ever you can have 2 same sigils one on each set.

Optimized build

In your build I think you do not have enough condition removal, you only have 3 when you traited the shouts. With the optimized build I changed Strength in Numbers to Purity, this will give you a passive condition removal ever ten seconds. By changing Shelter to Signet of Resolve you have another passive condition removal every 10 seconds. So now you have 3 on demand condition removal and 2 passive condition removal. but if you still want to use the traits from you original build i would suggest you change one of you shouts to Contemplation of Purity, this skill turns all condition you are suffering from in to boons.
