FATEs Infinitely Spawning Mobs Giving EXP (Possible Exploit)

Time: 09/11/2013 - 1:38AM CST
Frequency: Recurring basis for all FATEs for gathering items or secondary non-objective mobs that infinitely spawn.
World name: Gilgamesh
Character name: Milky Tea
NPC name: Milburh / Twin-tongued Addison
Monster name: Milburh the Malicious / Twin-tongued Addison
Class/Level: Lv. 49 Warrior
Party or solo: Solo or Party, N/A
In-game time: N/A
Area and coordinates: X26 Y21 Northern Thanalan
Steps:
1. Dark Devices - The Bait initializes.
2. Lunatic Lambs (objective mob) and other group of infinitely spawning mobs (don't have names on hand) appear.
3. Players are able to disregard / ignore objective mobs and focus on non-objective mobs and able to gather potentially not as intended amounts of EXP. In the neighborhood of 100,000-200,000 EXP in the span of ~14 minutes.

Other Notes:

This same bug / potential exploit applies to any FATE where mobs continuously spawn that are not a part of the FATE objectives. Gathering item FATEs being the primary other.

Yeah - that's the "Don't kill the sheep you NOOB!" one ... should be really fixed as some players getting really agressive around those if someone (try to) play it as intended. I actually always have a big urge to walk in and start killing the sheep everytime someone shouts this in there ...

I am not sure if SE has a queue system for posts on this forum, or if it's just whichever one garnishes attention. So, I'm going to bump this in hopes that we can get an answer sooner rather than later. :)
