You aren't forced to use a glyph. If you and your guild feel that missing ~one taunt out of ten is an acceptable risk then don't use the glyph. If you and your guild feel it is unacceptable then use the glyph.
A lot of people seem to think that glyphs are supposed to make our characters stronger by buffing a specific skill. This is the case with many of them however glyphs aren't there just to help us capitalize on the strengths of our class, some glyphs exist to eliminate a weakness. I more or less have to choose between the 8% hit glyph or a bonus to the healing I receive while frenzied regeneration is up. It's an easy choice to take in my case as I have little trouble with survival and believe missing two taunts out of a hundred is much more acceptable in terms of risk than one out of ten.
