Etiquette/Tips in CM

-The entire instance can be explained by "Kill adds, move out of red". That strategy covers every boss fight except the 4th, which is just a gimmick fight.
-Do NOT tank the second boss by the far right door. The key that drops can become stuck in doodads on the ground, making the instance impossible to complete.
-After the 2nd boss is killed, all the trash can be pulled to cannons.
-Do NOT start cutscenes while mobs are being pulled to cannons. While players will become invulnerable during cutscenes, your cannons will not be.
-When pulling mobs to cannons, DO NOT STAND IN FRONT OF THE CANNONS. The person kiting should be at the side so that any directional abilities will not target the cannons. Tanks should also use stuns on Colossus/Vanguard/Reapers.
-If the first set of cannons are down, you can always use the second.
-You should NOT "always" use Return after 3rd boss. Sometimes it is faster for one tank to Return so that he may pull the towers, but it is NEVER better for the entire party to use Return.

4th boss explained:
-Load 4, Fire 4, Gather adds in middle, Load 1, Fire 1, then Load 3, Fire 3.
-The shot after the adds spawn will kill all the adds without DPSing having to do anything (and will not summon more adds, because adds spawn at shots 2/4/6. Tank/heals just grab the adds and bring to middle while DPS stay on cannons/missile piles. DPS NEVER have to use their skills against adds on this fight.

And yes, this instance can probably be 4manned. It only requires 1 tank and 1 heal but that does not mean its okay for you to join DF AFK and do absolutely nothing. This place is so easy and doesn't require strategy or coordination, but you can still play smart and save everyone time and headaches.

Thank you for this..
I'm always looking for advice on dungeons, so this will be getting bookmarked...
Cheers.

It's faster to just load 4 fire 4, then put all the adds in the middle and load 4 fire 4 so you skip the next round of adds.

Actually with a decently geared group its way quicker to NOT kill the adds for the first 2 bosses and just nuke the boss itself. You do have to do this for the 3rd boss as he iwll become immune to dmg at one point and cid will bug out and not remove the immunity..

and no its not quicker to do 2 times 4 cannons on last boss as you only need 2 shots, not 4 (for 2nd round), and waiting for the 3&4 barrar to fill takes longer then to fire 1 and wait for 2nd cannon to be in range again

lol, okay, maybe I need to explain the 4th fight even more....

Boss takes 8 cannon shots to kill.
Adds spawn at every 2 shots you hit her with.

Load 4
Fire 4
4 adds spawn
Bring adds to middle
Fire 1 cannon
Wait for others to load
Fire 3 cannons
Boss is dead

Also, while you CAN skip adds for first boss easily, if you try and skip adds for the second boss, you will likely die in a pug. Premades can do it, pugs cannot. It is ultimately not worth the risk to skip adds for second boss, especially if you're playing in Duty Finder.
