So lately many people have been feeling like framework revamps have slowed down and that it's taken an unusually long time for new ones to come out. I wanted to find out if this was true, and if it was just how true it is. So I went digging through old PTS patch notes, specifically looking for the first time that patch notes were posted for a given revamp. Here are my results:
Heavy Weapons_________________March 2016
Whole Bunch____________________July 2016
PA/Laser Sword_________________November 2016
Single Blade____________________June 2018
Note that the "whole bunch" entry refers to that one time that we got like 3 pages worth of power changes to a great number of power frameworks all at once, and that it also includes the things that Darkness and Infernal got, which really nails home that those were not revamps, which is why I'm not listing them separately. I'm also including it because of just how big it was, and because it added a lot of changes to things that affected all frameworks simultaneously, so I would say it effectively counts as a revamp of its own. So let's throw some numbers around.
2016 - 6 revamps - 1 revamp per 2 months
2017 - 4 revamps - 1 revamp per 3 months
2018 - 2 revamps - 1 revamp per 6 months
Yup o3o that's a pretty decisive downward trend, especially considering we're only halfway through the sets. However it does put a question mark on the theory that the subscription change caused things to slow down. 2016 also brought us the cosmic revamp, the qliphotic warzone, TA, and the nightmare invasion. 2017 brought us High Noon. It's clear that the downward trend in activity had already started in 2017, and by the time 2018 hit things were already in low gear. We had already gone many months without a power review by the time the subscriptions change hit and overall the year was already looking like it was being devoted mainly to updating events.
So yes, power reviews have definitely slowed significantly, but the reason why is still likely unknown to us. Maybe they decided to devote a year to "under the hood" changes. Maybe they changed their process and are spending more time cooking things before putting them on PTS. Maybe DOOOOOOOOOOM O3O. Or some other possibility.
