For the
0/56/15 spec, wouldn't it be a good choice to exchange the least dps-increasing glyph for glyph of life tap? yes, you will probably lose personal dps, but instead you will buff the raid further, which in the should lead to a higher raid dps. Which glyph should be exchanged? I think it would be about an additional 15sp to every member of the raid. I also suppose glyphing life tap includes lifetapping every 20 seconds. I'm not sure if it's better for the raid (locks -dps <= raid +dps?), maybe somebody can help?
Edit: GJ so far Zakalwe, really helpful for all locks.
Edit2: Could you also do calculations for all specs with _DG? Since the demospecs probably doesn't gain at all using DG, whilst affli will, I think it should be in your calculations as well as a spec variation.
