You're basically saying Whitesmith is not so broken, You probably using Whitesmith at the moment and doesn't want to get it nerf'd..
Whitesmith doing 110k Tomahawk w/ ultra high speed and you're saying its not broken. Whitesmith can even cast Pnuema and have 300k+ HP. How is that not broken? Sniper damage sucks, That's why nobody uses it for pvp. And remember Sniper has no evade skill, Like GS(Charge atk/Adjustment) and Whitesmith(Pnuema) have.
And just like you said, Range classes were meant to be lowhp, But then. How are you going to explain Whitesmith having high damage high MHP while doing High-Speed spam?
