I'm not saying it is, nor do I want it to be. I've played WoW for about 3 months top in my lifetime lol. FFXI did have reraise yes, which if anything, enables this strategy even more and further validates it. I'm not saying this isn't an exploit, or it is, I'm saying I don't think it is based on my experiences with MMO's and how this strategy has popped up in my shapes, ways and forms over time (losing hate, recovering, continue with fight).

It all comes down to if the moogles not aggroing to sight is intentional or not. If not, then it's a bug which is being exploited. If however the moogles aggro behaviour is as intended there is no exploit here.
