They make it easier because the people who already have the gear and could do it before they nerfed it will only be focusing on T5+, while the people having issues with T2-T4 will still need the gear, so they will have to actually spend time to catch up.

Either way, nerf or not, the hardcore will be ahead, and progression will not be handed out where it matters (Leviathan, T6-T8 etc)
