Well i personalty was never bothered by the shorter respawed time nms that were like 1 hour or up to 4. I myself found hnms worse becouse the fact people want and so many infact that you have such a large compititions they bot claim just so they will get there gear fast and can move on or make gil off the game they do not want. I am sure people could have botted much faster respawning nms but they spawn so offen whats the point in constantly botting when people have more of a fair chance to get the nm do to the fact it just spawns more frequent.
