I'm just using the general forum clichés when talking about things. Dead in a week is the general talk about everything.
Gauntlet is the first instance in ages that will not be dead in a week because it doesn't allow back to back farming.
In regards to sector 10, then we don't know what's going on with that in the future. It was clearly stated that bounties disappearing NOW was a mistake, and that there were going to be much bigger changes associated with it than just removing bounties for the sake of it.
That part is just ignored by everyone. What if the future of S10 is no different than now, with a purpose to farm it existing.
Of course, since that part is ignored, everyone will in a month come crying about how they all leveled their perfect 150 twinks and now that sector 10 as promised was updated they are all going to quit because noone told them so... It'll be fun again to see how it's completely impossible to communicate anything to people playing the game.
