Have you checked the gear on the player you are accusing of exploitation? The answer is obviously no, as there is only one 384 tier piece on that player whereas, other ones in addition to those swords are all higher than the LFR level, hence, they've dropped from the normal lockout, and, moreover only the first four bosses of the instance is available for the kill on LFR.
If you are to go up against this you are either delusional or of the Zandalari Tribe...
