Critical strike rating becomes a whole lot less valuable at 100% enrage uptime (and 100% BT crit, which is pretty much the same thing, said in a different way), which is easily reached with the recklessness glyph. Having the 4 set bonus means that this delivers you a guaranteed 12,6% enrage uptime and a guaranteed 5 Raging Blows. Not using the glyph would result in a guaranteed 8,6% enrage uptime.
Seeing that more raging blows are going to benefit from the 30% extra crit while using the glyph vs less raging blows benefitting but having more chance to crit we can quite confidently say that the rest of the glyph effects even eachother out quite well.
Thus effectively using the recklessness glyph grants us 4% more enrage uptime. Obviously we have to take into account that we might have critted with blood thirst either way. The calculations for average blood thirst uptime during an 18 second window are quite complex so I doubt it's worth fully calculating it here but very very very rougly taken we can cut the benefits in half. This leaves us with the recklessness glyph granting us 2% more enrage uptime.
Assuming our enrage (example) increases our damage done by 15%, a 2% extra uptime will grant us an overall 0,3% damage increase.
This might seem little (and it is so), but I really doubt that dealing 10% more damage on whirlwind on a single target fight is going to result in a net gain of over 0.3% damage done. Try to find me a SINGLE TARGET boss log where whirlwind deals more than 3% of the character's damage and I might of course reconsider my opinion.
Simply stating that recklessness glyph is bad while not proving that the other glyph is any better is quite silly though.
