So after doing tons of dungeons I realized the ranger can take a few hits and does decent damage but one thing I couldn’t find was a good distance to stand, I know 30 meters is where you get max damage, but I think I could go further maybe 100 meters, so I am proposing you add an additional buff to the rangers skill that increases damage the further away you are from your target, if I hit the target from 30 I do good damage but I wanna hit my target from 100-115 and do insane damage. The further you are should make your damage higher and the more your bar is charged up from a further distance the the more damage you should do so to explain.
30-49 meters and a minimum bar should do 3k damage at least with level 30 gear.
30-49 meters and a middle bar should do around 9-10k
30-49 meter and a full bar should do 18-20k damage
50-89 meters and I minimum bar should do 2k damage
50-89 meters and a middle bar should do 11-12k
50-89 meters full bar should do 30-33k
90-115 meters minimum bar should do 1.5k
90-115 meters middle should do 13-14k
90-115 meters max bar should do 70-77k
Anything higher minimum bar should do 1k and a 100% crit
Middle 15k and a 100% crit
Max 83k and a 100% crit
I think the one flaw would be if the boss room is to small for anyone to get 50-100 meters away from the boss.
