They'll be done when our core developers have the time/motivation to write them. There's a long core to-do list, and this is quite honestly pretty low on that list. Be patient, or see if you can hire somebody to write these.
Edit: I stand corrected xD. r16914
Search the files for the 'monster' command, and delete the line for any monster you don't want.
As I posted, eAthena does not have the guild2 merge, so you have to edit all 10 files in that folder (not the auto-start file).
npcshopdelitem "card_mob#miniboss", 501,4027,4049,4055,4061,4091,4093,4095,4105,4111,4147,4153,4170,4273,4292,4344;
npcshopdelitem "card_mob#MVP", 501,4074,4127,4210,4246,4410,4419;
I think that's all of them.
Did you comment out the default controllers?
//= Be sure to disable the default agit controllers!
//== npc\guild\agit_controller.txt
//== npc\guild2\agit_start_se.txt
To remove monsters, delete the spawn code from trunk/npc/guild/agit_main.txt and trunk/npc/guild2/agit_main_se.txt.
