Walkthrough
Here is how I succesfully finish this quest with Heroes(Monk, Elementalist and Necromancer) and Hentchmens(war, mesmer, elementaliste, and Paragon). My charactere is a Monk. When the quest begin there are 3 groups of monsters that gonna rush you. One from left side(#1) and two from right side(#2,#3). Rush the left side group(#1) and kill them. When you kill them, another group spawn(#4). Kill them. And another group spawn again(#5), kill them. After that, its tricky, you have 15-16 monsters(#2,#3) on the quest starting point. They are all linked. You have to rush them and kill healer fast. (double meteor shower is pretty usefull) When you lose 4 members of your team, retreat and ress them. Kill almost all the monsters group until a new group (#6) of monster spawn on right side. Dont kill all the monsters from group #2 and #3 because you gonna make the group #7 spawn. Keep spawn separated like that, kill #6 without killing the last of #2 group. and kill everysingle group that spawning. At the end, the Margonite Seer Spawn (with a group of monster) they come from left side. Kill them to finish the quest. Hint: Keep few candy canes in your bag, that can help.

Note

 * A "They're on Fire!" Paragon and a Searing Flames Elementalist will reduce all of the damage received by party to a minimum, having "Incoming!" as the paragon’s elite also helps to reduce damage even more.
 * While minions are not very effective damage-wise against margonites, they are very effective at soaking up damage caused by the Margonite Reapers' Mystic Twister, extra targets means that there is less likely of a chance that the spell will hit you. They also serve to hold the attention of Margonite Executioners while you are focussing on the Clerics.
 * Due to the large number of enemies, Lightbringer's Gaze is a very good mass interruption as well as AoE damage spell. Make sure you bring it if you have it, and use it early and often.
