Guild Wars 2

I’ve been trying to find a good boon build, I’ve been running tests with “Concentration Training + Mighty Roar” now Concentration Training doesn’t seem to boost the boon at all and the Mighty Roar is meant to last 12 seconds but when applied it only lasts 9 seconds.

Is it a bug or am I just miss reading how it works

Not a bug. This trait only takes affect when either you or your pet is in combat mode.

Ok that explains Concentration Training, but that doesn’t explain why Might Roar unless its a bad description. It clearly states 12 seconds but only lasts 9 seconds.
