Ranger has a few masterwork perks that give the range more melee damage or shield on melee kill. The problem is that these perks are trying to benefit the part about Ranger that nobody ever uses. Melee on Ranger is so boring and not worth it to have any inscription or perk for it, you'd only use it to prime an enemy but that's it.
I suggest to remove all the masterwork perks that benefit melee and actually make some cool perks that benefit the way Ranger work.
Why would anyone want perks to increase melee damage on Ranger that has a 2 second CD and is average at best? These melee perks should be moved over to Interceptor if anything.
