It may be reborn in 3.1 but it really comes down to how they will handle the new mats in 3.2, the potential new scrips and such with new favors and rare mats to obtain. As long as they don't backpedal in 3.2 and have said items only available through the new scrips it will be fine, but if they don't then we'll be back at square one.
Thinking of the long haul, I think it would be wise if Legendary nodes took a step back in 3.2, or more like those nodes could get a new scrip that turns them into 12hr nodes instead of 24hr nodes.
Though quite honestly if the whole node mentality continues in the same process as 2.0, there is gonna be a huge amount of unspoiled node bloat which honestly doesn't make it as fun, maybe we'll get lucky and they will adopt to using favors more instead of time based unspoiled nodes.
I'd much rather farm favors and be able to use 5 favors to farm adamantite ore for 25 mins then have to wait every half hour for the node to spawn.
