Unwashed ranged classes are a waste of time?

You are wrong. Wrong. Wrong.

I didn't start HP washing until my mid 16x's, NEVER leveled with INT equips before that and I still am capable of battling EVERY boss to date. I barely have 5.7k HP WITH a MoN and there's nothing in the game that I can't do.

That's usually how it works after devoting thousands upon thousands of hours in an attempt to reach near end-game.
