I definitely could see timers being increased on all of them.
I also still vote that artifacts be changed. If we are talking about the 'fairness factor' and that is the reason all perzes are going to be gone through and made their current stats. Then you also have to look at that in regards to timers on artifacts. I believe that all perzes of artifacts should have timers. OR timers are gotten rid of on artifacts and posibly work out new load locations, different stats (since they were changed in this port and pretty messed up, many ruined). In old port, sure they were hoarded, and without timers, sure they will be again, that's inevitable. But there will be a market again for them. That will help also help further the economy as well in my opinion.
Along the lines of this I'd say that any people that have older perzes of items on the unperzable list shouldn't have them and be given the one free perz in exchange, OR the item be taken off the items not to be perzed list. Because once again, this goes against the 'fairnes factor'. Also that list is 4 years old, and a bit outdated in my opinion. So should most certainly be looked at.
That's just my take on artifacts
