Tempest is the only one spe woth a bad new weapon. Mesmer àd revenant shield are amazing, dh bow is great. Staff drood is really good, reaper greatsword is fine, thief staff is ok and hammer ingi is mesmerizing. We can discuss about berserker brcause the weapon is not so bad but no usefull. So they have to do such a thing with this warhorn.
A lot of long cast, in fire attunement there is a great zone but just for pve (too long to pop).
Water is fine (with a dispel in the 5 it would be relu better).
Air, hum it´s really strange for idea. The globe is really strange.
Earth is fine but it miss an immune. When we compare, focus or dagger are really better than warhorn… It´s not normal.
