cause i've been nagging Goblobsters about these events for a while.
from what i've read, a full alliance can do this to great success. it's always 4 NM at each flag, who all aggro the first person to touch the flag. i think the same type of setup we use at HN Garrison 20 will work, minus the kited mob, as we will not have a second wave to contend with.
it seems that the NM beastmen spawn with random jobs, selected from the pool of jobs available (gigas, for instance, only have 4 jobs). this means you can fight Yagudo SMN that will astral flow, and Quadav PLD that invincible. this means that depending what jobs pop when the banner is touched, strategy may have to change. it could be simply "pwn the whm," or it could be more complicated (someone from a Leviathan-based EF LS mentioned in the Guides section of Alla that if you kill the NM BST's pet, he will charm your pt members.. >.< ).
the goal of the event is to clear all 5 flags as quickly as possible, so having spotters outside the alliance at the various flag-spawns would help facilitate "Conquest Chains".
there is not much in the way of lewt that drops from these, at least that i can tell from what research i've done. the biggest reward, other than the reward of kicking *** at an event that requires high levels of player coordination, would be the CP bonus. the 30 cap EF is reported to grant 3k CP, though your nation must gain control of the region in the next tally in order to claim your prize from the gate guard.
in additon, EF events can be scheduled to coordinate with Garrison events, which DO have a lot in the way of lewt that drops.
