I’d like to suggest one of the following to promote build diversity among Engineers in a pvp setting.
*Change Fumigate to remove 1 condition from the Engineer upon use.
*Change the Elixir Gun toolbelt skill Healing Mist to remove 2 conditions from the engineer upon use.
The reasoning behind allowing the toolbelt skill to remove 2 is the long (40 second) cooldown. Fumigate is on a much shorter cooldown and would be fine removing one condition.
