The first new Heroic in 4.3 is End Time, taking place in a desolate future where Deathwing has won. Here, you’ll need to deal with two random Echoes at their respective Dragonshrines before you can head to the final boss at the Bronze Dragonshrine.
At the Azure Dragonshrine, you’ll find the Echo of Jaina. You’ll need to collect 16 fragments before you can fight Jaina, but there are also several packs of 4-5 Time-Twisted soldiers to deal with.
- Time-Twisted Footman can Thunderclap but otherwise not a major worry.
- Time-Twisted Rifleman toss out Multi-Shot, make sure they’re not aiming at your healer.
- Time-Twisted Sorceress will Blink around and may aggro other groups if they’re too close, so try to pull when you’re away from nearby patrols. She’ll also be casting Arcane Blasts.
- Time-Twisted Priest should be the first CC or kill, they’ll be casting Fountains of Light.
Now you can certainly collect all the fragments without aggroing any of the packs, but it’s a good idea to get rid of at least the 2-3 closest groups from where you came in. Jaina Blinks around and may bring a wandering patrol into the fight if you’re unlucky.
Once the area is clear and you’ve got all the fragments, Jaina shows up and you can engage her. When she drops a Flarecore, someone should step on it after making sure no one else is standing close by. After every blink she’ll cast Frost Blades, avoid them or you’ll get stunned. Frostbolt Volley should be interrupted when possible, but the rest of time she’ll be spamming Pyroblast on you which can’t be avoided.
The Emerald Dragonshrine is where the Echo of Tyrande waits. To get to her you’ll have to deal with a seemingly endless stream of Time-Twisted Huntresses, Time-Twisted Nightsabers, and Time-Twisted Sentinels. They all have the In Shadow buff though, so you need to drag them into the beams of moonlight to be Moonlit before you can kill them. Kill as many of them as you can before the moonlight fades, then move on forward to the next beam, and so on until you finish them all off and you get to Tyrande.
Fighting her is pretty simple. She won’t move at all from her rock so spread out in a circle around her, but casters should stay back because of Dark Moonlight. Make sure to interrupt Stardust, and if she’s facing toward you when casting Moonlance, move sideways away from her line of sight. She’ll also summon two Eyes with Piercing Gaze of Elune, just move toward or away from her to stay out of their path.
The Obsidian Dragonshrine is the Echo of Baine‘s area. To get to him you’ll have to deal with the groups of Time-Twisted dragonkin. Be careful when pulling, as the patrols wander pretty close to the stationary groups. CC the Time-Twisted Seer if you can, or kill it first. Make sure to move away from the lava fountains from Call Flames and keep your distance, especially if you have Sear Flesh on you. Move out of the Time-Twisted Breaker‘s Break Armor and Rupture Ground cone effect. Face the Time-Twisted Drake away from the group so Flame Breath doesn’t hit them.
Baine is on the farthest platform. Whenever he does Throw Totem, have someone grab it and Throw Totem back at him to stun him. At certain points he’ll jump toward a party member and Pulverize the platform they’re on. If it’s the one you’re on, swim over quickly to another one, because he’ll be getting the Molten Axe buff as long as he’s in lava which stacks a debuff on you, though it can be cleansed (you do gain Molten Fists in lava too but fighting in fire in generally a bad idea).
The Echo of Sylvanas is at the Ruby Dragonshrine. Clear your way through the packs of Time-Twisted Scourge Beast and Time-Twisted Geists. You should probably kill the Geists first, to minimize damage from the Beast’s Wail of the Dead. You can skip the Time-Twisted Shadowtalons off to the side.
Sylvanas is a simple fight as well, you’ll want to be slightly spread out so her various arrows don’t hit more than one person (Black Arrow, Unholy Shot, Blighted Arrows), but stay all on the same side of her. When she starts her Calling of the Highborne, Risen Ghouls will spawn in a circle around her and slowly move in toward her. Pick one Ghoul to kill quickly, then run out of the closing circle and keep your distance until all the Ghouls are sacrificed.
Once the Echoes are down, you can finally enter the Bronze Dragonshrine. There are two groups of Infinite dragonkin, composed of two Infinite Suppressors and two Infinite Wardens. Kill the Suppressors first to avoid their Arcane Wave and Temporal Vortex.
Once you kill all the Infinites, Murozond will fly down. Have a ranged or healer stand near the hourglass while you tank Murozond. During the fight he’ll be casting Temporal Blast and dropping Distortion Bombs on people, just move out of the glowing yellow circles left on the ground. Infinite Breath means no one should be standing near or behind you. One way to do this fight is by slowly moving him in a wide circle around the hourglass (though realistically you probably won’t get more than halfway around), once you run out of room or there’s no room left near the hourglass, or people are out of mana/about to die, have someone hit the hourglass to Rewind Time. This removes all the Bombs and resets your position back to what they it was at the beginning of the fight. You could also just hit it at each 20% mark, which allows everyone to reuse their cooldowns more often. He does a lot of damage too, so don’t be afraid to use your tanking cooldowns often.
