The case of the 90 second cooldown
With the newest event schedule, Niantic shared the following:
"Starting this quarter, each quarter, we will evaluate the following temporary changes added in early 2020 to determine their impacts on gameplay while considering real world circumstances:
- Portal cooldown between hacks to be adjusted up from 90 seconds
From the sounds of it, Niantic is at least thinking about reverting the Covid boni back to either the original values or 'adjusted up' from their current values.
While a smaller set of people don't like the 2x L7 Resonators disappearing or the AP for recharging going back to 10AP, the overwhelming majority of people do not want the 5 minute timer back, going by the comments in the announcement.
So, I invite you to make your case why or why not the cooldown for hack should stay at 90 seconds or why it should be adjusted up. While they don't always reply, I'm sure Niantic is at least reading, and seeing that they didn't outright state that they want to put the cooldown back up to 5 minutes (only 'adjusted up'), it seems like they already know that agents would break down their doors if the cooldown gets reset.
