That won't happen. Weapons like Fatebringer, Fang and VoC are so good that they'd instantly make Y2 gear irrelevant if they were bumped up to Y2 levels, especially as Luke Smith said that there would be no more legendary elemental primaries going forward. It'd be good if the old raids could drop Y2 exotics from the appropriate bosses/chests or operated a smart loot system. On hindsight, they should have graduated the progression of Y1 weapons so that they became less relevant over time, rather than halving their power and making them irrelevant in a matter of hours. However, there is no reason why we can't have, at the very least, Y2 versions of raid armour. Outside of the heavy ammo boots, which would be better than anything else on offer at the moment, updated VoG, CE and PoE armor would be great to see without breaking or changing the game's dynamics.
