I would like to note that you
CANNOT stack several glyphs of the same type to increase the effect.
Upon attempting to inscribe a duplicate Glyph at the Lexicon of Power you recieve the message:
"That Glyph is already inscribed in your spellbook."
A very useful glyph for any tank. In PvE it provides additional movement in tricky fights and in traveling - replaces unholy presence.
I'd say the worst part is that Bone Shield usually doesn't last long when it's up, considering it's supposed to be used as a defense cooldown rather than an active part of any rotation. When you're not being hit, it's very beneficial -- this is 6% faster than the Tuskarr's Vitality enchant, matching Unholy Presence while letting you stay in Blood Presence. But few tanks will ever be "not getting hit", and when they're not getting hit, they can easily switch to Unholy Presence anyway.
Honestly, thanks to this glyph Bone Shield is almost completely useless for PvE content. Bone Shield only has 4 seconds of up time if you're taking hits every 2 seconds or faster and while it wouldn't be much a fourth charge would have boosted the up time by 50% from 4 to 6 seconds. Even after having been nerfed a talented Icebound Fortitude is still far far superior for the cost. I'll grant that 20% reduction to major hits is very useful if you can time them, if you need to time them, but between human nature and how the rune regeneration system works now it'll be a serious hassle for a lot of players, especially if they regularly use Blood Tap to get the 4p10 bonus resulting in it being on CD when they need it to pop Bone Shield.
Still, I can see some use for this glyph in PvP. If you combine it with Chains of Ice or have other players with rooting/slowing abilities you can more easily dictate range while engaging in PvP as a Blood knight. It also, incidentally, fits in with Blood-Caked Blade being put in the Blood tree since it's not particularly easy, or useful, to fit it in with a solid tanking build, and as such indicates that Blizzard apparently stuck a few talents in there for PvP usage.
At the very least it's not like they made a mistake and left Blood as a DPS/tank hybrid spec. after all. Right? >.>
If you are
leveling as Blood
, this is a great first major glyph.
1. It's good because you dont have movement speed buffs from Unholy Presence until you get it at level 70. If you spec frost you do get mounted movement speed bonuses.
2. It is great for questing and solo play, plus covering ground faster in instances.
3. Helps you stay ahead of dps in dungeons.
In Mists of Pandaria this glyph has changed.
OLD: Glyph of Bone Shield - Increases your movement speed by 15% while Bone Shield is active. This does not stack with other movement-speed increasing effects.
NEW: Glyph of Icebound Fortitude - Reduces the cooldown of your Icebound Fortitude by 50%, but also reduces its duration by 75%.
