Finally, a true tanking minor glyph. I'm thinking this will be a hot seller in the AH for anyone who learns it first.
This glyph is discovered through Minor Inscription Research.
Well, this puts protection Warriors in a fairly unique situation as far as I'm aware. With this, there are actually 4 Minor glyphs that are good for tanking.
Glyph ofBloodrage, Glyph of Charge and Glyph of Thunder Clap together with this glyph are all desirable. I'm guessing the Thunder Clap glyph will be the one biting the dust, but I will keep thinking when bad situations happen that "Gee, if I still had my Thunder Clap glyph, that dps might not have been smooshed".
On the other side of the spectrum, I still only have 2 minor glyphs on my Mage. There simply aren't anything worthwhile to put in the third slot.
I disagree about the bloodrage glyph. Since the healthcost is only a % of base health, the amount lost relative to a tank is trivial. For a human warrior with 30k health (roughly 10man gear), that's 4.3~%. You can only use it once a minute so with 1299 damage over a minute means... 21.65 damage a second.
When healing is limited (Loatheb, soloing with bloodthirst), I can see the value. Everything else? Not really.
You guys are forgetting the really good reason why Bloodrage is a waste of space.
Who hasn't gotten a healer that doesn't heal you when you get damage? I get healers that heal me even when I'm full health or eating a feast.
Glyphs happen first, and then talents.
Commanding Shout has a 2 minute duration.
With the Glyph, it is now a 4 minute duration.
With Booming Voice, it increases by 50%, which is another 2 minutes, for a total of 6 minutes.
With just the glyph, it's 4 minutes.
With just the talent, it's 3 minutes.
It seems, as it does in many cases in this game, it comes down to preference.
Pros: Extra range on chasing down runners, getting back faster to the boss after a knockback or repositioning.
Cons: Isn't terribly useful on bosses where you don't have to do a lot of moving.
Pros: Worry free use of bloodrage on cooldown.
Cons: Only saves you 1300 health every 60 seconds as someone pointed out.
Pros: Substantially larger TC radius, great for multiple mob packs.
Cons: Isn't useful for single boss, single target encounters.
Pros: Frees up a GCD, less worry of it falling off.
Personally I think I'd stick to the classic 3. With booming voice Commanding Shout is 3 minutes, which for me isn't too bad. While a 6 minute CS would rock, I feel it's more of a luxury glyph while the other glyphs are possible deal breakers in specific situations.
I prefer to save it for when I need it. I'm sure you didn't mean to state that in such a hard and fast rule but thought I'd throw in another couple of cents.
Rage management can mean the difference between ending a fight with no rage or with a bar full of rage. There's some luck involved but if you have a clear threat lead on a mob and it's nearly dead, you can focus on another or just be skinflint and auto-attack and use revenge. Now you got a full bar of rage and the cooldown still available.
Think gauntlets where you need to be able to pick up any and everything as they enter combat. Or that hallway just after Volkhan in HoL. I use bloodrage as soon as I enter combat and the statues-turned-mobs will beeline immediately.
And sometimes I'll just save it for between pulls to keep my rage up if I can't find critters to taunt to keep myself in combat.
Another thing to consider if you are raiding the t10 4p set bonus makes Bloodrage glyph useless and gives you some mitigation when using Bloodrage.
Come Mists of Pandaria, it seems the item ID for this is switching over to Glyph of Thunder Strike.
The glyph will change a warrior's Thunderclap to cause lightning to strike all around him, similar to the old animation for the Druid's Hurricane.
Seems kinda silly, but stay on this page, head to the upper left corner, and switch over to WoWhead's MoP database. The ID sticks between glyphs.
OLD: Glyph of Command - Increases the duration by 2 min and area of effect by 50% of your Commanding Shout.
NEW: Glyph of Thunder Strike - Your Thunder Clap visual includes a lightning strike.
For extra annoyingness, be sure to macro 'Here comes the thundah!' to this glyphed attack.
Am I the only one who sees the tooltip for this glyph in my inscription window stating it applies to both Protection as well as Arms specs?
What really annoys me about this glyph is the fact that the lightning doesn't come from clouds or anything. It literally comes from nowhere. If you look up or zoom out far enough, you can easily see that, and it bothers me.
Very first use: hmm kinda cool.
It opens the spellbook and just activates Thunder Clap instead of applying the glyph.
