With the glyph in one of our major slots, the totem will have a 5 minute cooldown. This means that a boss fight at 300 seconds or less then the glyph is a total waste. At 360 seconds you only get an additional 60 seconds (half the totem's total uptime). Then at 420 seconds the glyph allows for two Fire Elementals to run their full duration.
Even on a single target fight having two ele's up will beat out the Glyph of Windfury Weapon-- at least in my sims at Stoney's gear level which includes Black Bruise and Cudgel of Furious Justice, two weapons with high damage numbers that should increase the benefit of glyph of WF. After running a few sims it became clear that even with those weapons and just a single target fight, the fire ele was over the top on longer fights. Add in some adds and it's well worth it.
The next question was, on which fights will the glyph be worth it? I went to World of Logs to find the median boss fight length to decide if we should be glyphing for Fire Ele in these fights. Here's what I found:
|ICC Normal Fight ||10s (secs) ||Glyph 10s? ||25s (secs) ||Glyph 25s? |
|Lord Marrowgar ||229 ||No ||243 ||No |
|Lady Deathwhisper ||263 ||No ||324 ||(1) |
|Gunship Battle ||n/a ||No ||n/a ||No |
|Deathbringer Saurfang ||266 ||No ||269 ||No |
|Festergut ||227 ||No ||280 ||No |
|Rotface ||219 ||No ||304 ||No |
|Prof. Putricide ||362 ||No ||495 ||(2) |
|Blood Prince Council ||300 ||No ||317 ||No |
|Blood Queen Lana'thel ||283 ||No ||318 ||No |
|Valithria Dreamwalker ||315 ||No ||352 ||(3) |
|Sindragosa ||512 ||Yes ||510 ||Yes |
|The Lich King ||982 ||Yes ||968 ||Yes |
And for Trial of the Grand Crusader
|ToGC Fight ||10s (secs) ||Glyph 10s? ||25s (secs) ||Glyph 25s? |
|Northrend Beasts ||400 ||(4) ||459 ||(4) |
|Lord Jaraxxus ||204 ||No ||263 ||No |
|Faction Champions ||210 ||No ||504 ||(5) |
|Twin Val'kyr ||173 ||No ||230 ||No |
|Anub'arak ||247 ||No ||462 ||Yes |
There are a few judgment calls in there, which I'll go into greater detail here:
(1) - Ldy Deathwhisper on normal isn't exactly a hard fight. The ele could have a good time attacking the boss but for the most part on normal mode I'd suggest passing on this glyph, unless your guild pushes up towards the 6 minute mark on this fight.
(2) - Professor Putricide in phases 1 & 2 can be done as a high movement fight or as a mostly stationary fight if you follow the strat to tank him directly under the green slime spawn -- something we executed successfully in Big Crits. Phase 3 however is very high movement and it's likely the Ele will get left behind. For this reason I do not recommend glyphing into it for 10s; in 25s it is likely to get used in phases 1 & 2 then be on cooldown for phase 3. Your call.
(3) - Dreamwalker is a high adds fight. Actually as far as tanks & dps are concerned it's an adds-only fight. I really don't recommend the FE glyph unless your guild pushes the upper boundaries of 5-6 minutes in there. Definitely guild dependent decision.
(4) - Northrend Beasts is a long fight and you'll definitely get use of the totem twice, but the odds are high that Icehowl will not be where you want him to be for Fire Novas and you'll lose that damage. I'd say you're better off not using it here.
(5) - Faction Champs have an AoE damage reduction ability so that high DPS guilds can't round them up and AoE 'em down. The Fire Ele does ~25% of its damage as AoE so the output is gimped a bit, plus there's a chance the opponents will target and kill it. Again, I'd say no to this in most circumstances
There are clear cases where this glyph will bring the maximum benefit. Namely, some of the hardest fights: Anub'arak in 25s heroic, plus Sindragosa and The Lich King on 10s and 25s. For this reason I highly recommend having a few stacks of the Glyph of Fire Elemental and Glyph of Windfury Weapon made for switch out on these fights. Use every advantage you can.
May all your hits be crits!
