How engineers are good farmers
First
Engis have self heals and medium armor which reduces chances of dying while farming.
Engis also have powerful buffs and debuffs to kill enemies faster.
The reduced use of stims causes stim build up
So u don't have to specifically farm stims to "farm stims"
Like everybody says a stim saved is a stim earned.
Engis are efficient boss solo-ers
Due to not weak armor and
Powerful buffs and debuffs so the boss doesn't kill u
While the debuffs do most of the work
Moments later u will get a green while
Ur op counterpart just respawned at the entrance with 40% health and mana
When group farming engis make the farming easier and less deaths will occur with our op friends
They also speed up boss fight with their renowned "DOTS"
So generally it would be easier to farm with engis
