I run a party with several rangers and since picking up this ability we almost immediately kill all low challenge enemies as soon as one of them gets a turn. (This is on PotD, with level upscaling)
While the ability is spammable, it notably only does good damage against 'easy' enemies. Against anything hard it suffers from low penetration, accuracy, and %dmg bonuses, as it doesn't get the standard attack bonuses from the equipped weapon. Spamming this against anything tough will just successfully burn out all of your resources and make little impact.
It does feel wrong to be able to spam through 10+ shots of this on easy fights, but on tough enemies where I need the weapon bonuses, it once again is mostly just useful for repositioning.
It reminds me of Brand Enemy, and how 1 paladin can set the entire enemy team on fire right away. Although, that was a valid strategy in the real-time mode as well.
Edit: Of note, Evasive Fire does not gain a bonus from Sneak Attack. This doesn't make sense thematically (shooting a guy isn't an attack?), but would further hurt the balance of the ability.
