just had a nice idea for a glyph that works around the idea nourish works.
Glyph of Nourish: Nourish put a Heal over time on the target, based on the number of YOUR heal over time Spells on the target.
1- 200 over 5 sec
2- 400 over 6 sec
3- 600 over 8 sec
4- 800 over 9 sec
5- 1000 over 10 sec
Im not sure of the numbers but this would just be a rough figure, the 5th HoT being "nourishes" HoT effect.
