I agree with what Sureal and Vold are saying here. My LS gave up on camping HNMs due to the fact that 3-4 linkshells would use bots to claim against everyone. As long as this game is going to have cheaters who use botting to gain the upperhand, I never want to see HNMs introduced with 24+ hour spawn times and 3 hour windows. I actually still really want forced pop on the current ones for people still working on their Black Belt (an lsmate has been stuck on adamantoise egg for a very long time now). :/
That being said, I absolutely LOVE the thrill of just fighting them. There's something just so cool about fighting a huge dragon! I would love for SE to release some new HNM-like monsters outside of abyssea just for the challenge and pure fun of it.
