I think there is a misconception that RV is a bad ranged career.
All of his ranged weapons are excellent with the exception of Throwing Axe, so long as he has ammunition sustain he can perform well as a ranged career.
Not to mention other bonuses to boot like stealth, free bomb dupes and party wide healing.
The only point I see in an RV rework is to:
- Differentiate the play-styles of RV/Engineer
- Bring RV closer to dwarf ranger lore
- Fix the scaling issues
His ammunition sustain can go from practically non existent to “I have more than I know what to do with” based on difficulty and other factors, his ammunition sustain only just becomes reasonable in Cataclysm. I’ve seen 20 minute Legend games with only 20 - 30 specials.
