If you're not playing with DP, than this Glyphe is mandatory.
I'm always forcing Proccs, so, overall, i've much more HP to spend for Heal or Damage.
So this Glyphe is not manadatory for me.
That this Glyphe is still really good
But nor for my Playstyle.
i can't say i understood most of that but, frankly none of that makes any sence not to use tv glyph.
if you are kiting then tv glyph is even better with exorcism that generates hp and provides damage reduction? unless i missed someting tv glyph is a must no matter what really.
