That's also a good point.
However, I think if they tuned the new HM ops for 75 gear, that target audience would just be to small.
There's plenty of people/guilds that have no problems at all clearing the current HM operations, but are still struggling with the NiM operations. Tuning for 75 would mean that they would be stuck at the sm versions, which is no challenge at all.
not to mention then what is the point of NIM ops if NIM teams are supposed to be getting the highest challenge and gear from HM. is NIM then just to reuse content?
bioware Austin really needs to be more clear about their plans for progression, right now the lack of consistency makes me concerned that they have no long term plans or structure for ops progression.
