Your right, it was only a disaster for them.
For others it was a major inconvenience.
And yet for others it was a minor annoyance
And then for the truely casual players it did nothing for them.
I’m glad I farmed my instanced NR gear before this change happened.
I main hunter and I got my Mara NR gear a month or two back, and did it for a few of my raids melee classes and one of our main tanks, this included constant resets for the rare spawns.
This change does hurt legitimate players to the point of considerable annoyance. Because I can reach that 30 instance cap fast by using multiple toons to reset instances for rare spawns.
I used my hunter and my lvl 40 mage to reset Mara 5 times each an hour fishing for the rare to help my guildies farm the NR gear they need. That’s 10 an hour, 30 in 3 hours, all resets spending about 3 minutes inside the instance fishing for a rare per reset.
And while waiting on the 5 instance reset limit I open world farmed. So needless to say this change has a considerable effect on players, not just botters but players, who are rare fishing in instances for needed gear, like NR gear for AQ … So glad I did it early lol.
