EC SM tactics

TL;DR tactics: Tanks, keep the two bosses away from each other (35m at least) to avoid them buffing each other. Every time Toth jumps, both tanks swap bosses. Zorn group (left group), if you're ranged DPS, stay at MAX RANGE at ALL TIMES and move away just before the jump (90%/70%/50%/30%/10%) to avoid Toth's debuff. If you get caught in the debuff, switch DPS to Toth until it wears off. Tanks, point Zorn away from the group to avoid unnecessary AoE damage. Zorn will stun the tank at times, but it's a BUFF, not a DEbuff, so you can just right click it away if you like, rather than using your stunbreaker. Kill both around the same time to avoid soft enrage.

TL;DR tactics for Stormcaller: Frontal cleave, point away from the group. Double Destruction, DPS need to BOTH take this attack for the tank, then get out of the way before Electric Discharge hits.
TL;DR tactics for Firebrand: One DPS stay on ground, dodge the red circles. Tanks will be hit by Incinerate Armour which will destroy all armour for 15 seconds. Healers, watch out for that.
TL;DR tactics for both: Every 20% or so, adds will spawn under nearby shields (always in the same place on SM) while the bosses spam mortars. Everyone go under the shields, kill the adds, then get back to their boss after the mortars are gone. Do not use AoEs in the shields or you will destroy it.

TL;DR tactics: One tank stays in the tower, plays some Minesweeper (and occasionally kill an add up there with them) and you guys are the sweepers. Move into the green, stay out of the red. Tank will decloak an elite which the sweepers kill. Someone will get a defusing kit. They, and ONLY they, step into the yellow, click the mine, defuse it. Rinse, repeat until we get to the boss, which is a simple tank and spank, though he will target a random player every so often and focus fire on them.

TL;DR tactics: Stay out of the walker's fire. Kill the bombers ASAP. Person who lands the killing blow on a bomber, run under the walker to knock it down. Everyone burn the walker. This should take two or three bombers, depending on DPS. Adds will spawn between bombers in three waves. Kill the Warrior first because the others are shielded until he's dead. After the walker's droid, Kephess spawns. Tank face him away from the group, he has a cleave. When he jumps into the air, stay out of the circles on the ground. At 60%, he'll pull us all in and do massive AoE damage. Run out of the circle. When he casts "Breath of the Masters", tank swap. The tank with the effect will start dropping purple circles everywhere for a while. This is a soft enrage and they never disappear. Drop them at the edges of the battlefield, then get back in.
