The 500/5000/50000 prescribed formula only gives you about 500,000 eHP, which for me isn't enough for any type of sustain to heal you particularly since you can get one-shotted by several attacks in Sanctuary, namely the Fallen Maniacs of Keep Depths 2, Savage Beast charging moves, Rakanoth's Charging move, a dead Molten affix elite with an aftermath explosion upon death, etc.
A balanced build is something that's comfortable by the player across any MP, you might be balanced for something lower level or higher level depending on the quality of your gear. Imagine the equipment you have but a cheaper version. All the principles of the build are in place but you have severely less CC%, CD%, IAS%, stat rolls, and res rolls. It could still be deemed balance.
I personally consider myself balanced but others could see it as one-sided.

I have enough DPS to take out packs that isn't drawn out, but nothing lightning fast. I like the playstyle I've been polishing since 1.03 with a hybrid focus but the desire to tank through damage.
Though I don't have the 200k DPS required by some in the Monk community, I enjoy being able to sit there on an arcane beam and just power through it without moving.
Repositioning quickly is okay, but I don't like running. I see some monks in public games just run away completely and fight white trash for spirit to spam spirit spenders for burst LS healing, only to run away again and repeat. Or Barbs for that matter, having to run to a pack of white trash to drop tornados to keep Thrive on Chaos running. The running away, just seems a bit weak and pathetic to me. Strategy sure, but not my cup of tea.
