druid and ranger
Depends on what you define as “dmg spec”. Ranger has very high dmg potential via pets (smokescale/bristleback) while having decent survability, which makes it very strong in 1vs1 (druid or not doesn’t matter that much in this regard, it just brings better teamsupport/utility). But you will be 100% reliant on those pets.
Glassy builds with the ranger as main dmg dealer doesn’t work very well though. LB gets countered too much by reflects/projectile destruction, blocks and LOS. GS burst is too slow/easily to avoid with low sustained dmg and sword has only autoattack as main dmg source.
here you have a dps powerranger build
