Crit is one of our less desirable stats hovering 10-20% buffed unbuffed after reforging gemming and the like.
Healing touch is 18460-21800 spellpower 186%
Regrowth is 9813-10954 spellpower 95.8% on the direct heal 7.3% spellpower and 2361 on the Hot
using the glyph of regrowth we have a guranteed crit but we lose the hot portion.
In the end after adding your spellpower a glyphed regrowth with nature's swiftness will heal for more than using healing touch except if you get a crit from using healing touch.

Healing touch 18460 21800 1.86 37194.42 83481.63 166963.26 88491.63 176983.26
Regrowth 9813 10954 0.958 19157.13 43455.19 86910.38 45166.689 90333.38
3k difference not that much at that spell level and big difference if healing touch crits
using bis increases spellpower to 31139 and even then the difference is only 4k so it seems that best choiice is to keep using healing touch just in case
we get that juici crit or shall we forget about the odd NS+HT Crit chance for the more consistent and higher NS+regrowth?
(anyone knows what tags can be used to give format? table doesn't seem to be working for me)
