Since we've already failed this mission once, I think we need to find a strategy to go with as opposed to trying to wing it.
The basics of the mission: Using this map for reference, the mission starts to the west at Hinon and proceeds east. There are 3 regular harbingers up the initial stairs and corridor marked by red Xs. There are a bunch of margonites lying in wait throughout the garden itself. On either side of the ravine in the center are two more harbingers makred by X. Across the ravine, there is the harbinger of nightfall marked by a yellow X. Up the two staircases on either side are harbingers to be killed for the masters level, marked by blue Xs. Every two minutes a patrol of margonites will spawn at the harbinger of nightfall's location, randomly run around either the left or right of the ravine, and head west towards the beginning, attacking any players or spirits they find on the way, and eventually killing Hinon which ends the mission.
Each harbinger is immune to damage and can only be killed by a light of sebhorin. One light spawns at the start of the mission by Hinon, and he will spawn another one every two minutes. (Not that we want to wait for that) When you drop a light next to a harbinger, the harbinger dies, a spirit of sebhorin is summoned, and a new light of sebhorin appears. When you use that light, the spirit that created it will make a new light at it's location. If the spirit linked to a light dies (to a margonite patrol), then the light disappears as well. You need 3 lights to kill the harbinger, so going back to pick up extra lights from the spirits is necessary at that point.
Wiki lists several strategies that are worth reading over. What they all have in common is that they try to avoid killing at least one harbringer. While the patrol frequency is always two minutes, the size and composition of the patrol group increases for each harbinger you kill.
I would suggest the "tactical advance" strategy as being the easiest.At the start, kill the first patrol, run past the first two harbingers, kill the third one at the top of the stairs and work on from there up the left side. Kill the harbinger to the left of the ravine by pulling him and his margonites towards the center of the ravine (to watch for patrols). Then go around the left of the ravine and move through the center and clear out as many margonites as possible without aggroing the harbinger of nightfall. (Since the patrols come from the center we won't be missing them) Once that is done we can kill the harbinger to the right of the ravine from behind, or we can attempt the bonus first. Then send a runner (or two) back to kill the first two harbingers while the group waits across the ravine to catch patrols, then have those runner(s) ferry 3 lights up to our group, then use that to finish off the harbinger of nightfall.
As wyrm pointed out, once a patrol group is finished you have to immediately start working on one of the static groups, so you have the best chance at killing them before the patrol group shows up. No waiting to catch your breath like we often did. We need to use something other than rebirth for hard res (ressurect/renew life/death pact signet/signet of return) so we don't have that additional downtime of rebirth. And not too many hard rezes since each harbinger gives a morale boost, and we'll probably fail anyway if we are dying that often. This also means we can't engage the static margonites constantly, and need to anticipate when to wait for the next patrol to come around.
While our skill choices as LoL are tight, we need at least one runner to ferry light of sebhorin around, and also in bad situations to catch aggro from a stray patrol. When going for the bonus, you ideally want to first lure the margonites on a staircase down to the bottom and fight them there, then send a runner by themselves up the staircase to kill the harbinger with a light, while the group stays below to watch for patrols.
Better coordination is also vital for this mission. This means everyone including our KKoP friends on vent, and a single leader who calls the shots for when to engage, when to back up, when to wait. If we wanted to be real precise, a stopwatch could give us a feel for when the next patrol is due, otherwise we need to watch and communicate for that patrol.
