Rules clarification

[Savok]

I just want to ask, did TMO engage with those 15 and win? i only ask because the rules state with sufficient force:

Q: Can we camp raid mobs?
A: If you choose to lay a claim to an unspawned raid npc, your raid must be at the npc's spawn point with sufficient force. (within aggro range of the npc when it spawns, with at least a 15 member raid party). e.g. (inside Nagafen's Lair) This is the ONLY way claims of unspawned raid targets will be respected.
