As an Engineer main, the Ranger is by far one of my favorite weapons. While it takes some skill to use well, the payoff is ridiculous and is overall a fun weapon to use. Also, 120 damage crits at any range is a godsend for a shotgun. I’ve jarateed off many friends with a lolcrit smashing them in the face.
The Rescue Ranger is a weak weapon in combat, shooting repair claws that do 60 damage at close range and 20 at long range, with a base damage of 40. But then again, the Engineer was never meant for shooting people to death. Instead, he has 128 DPS aimbots that fight for him. The fact that it has the lowest DPS of all Engineer primaries, it’s hitbox is not the size of a truck and it isn’t the Frontier Justice means it’s rather uncommon to be seen used by most players. Don’t let that put you off though because the Ranger has two amazing practical uses(other than being a Ninjaneer): sentry transportation and supporting other engineers from your own nest’s safety.
