Something must be completely wrong with this perk:
"Improved Camouflage - Camouflage no longer breaks from dealing or taking damage."
It would basically make survival hunters immortal WHILE attacking, since no ranged class can target/attack you with anything but AoE spells, no CC, no nothing O_o
EDIT: With Glyph you are also invisible ONTOP of that. So yeah immortal and invisible. Best of luck opponents!
