Typical for season open in D1K is that the entire map is taken within 15-20 minutes. Usually it is more than one guild taking the map, but if it is an imbalanced map, one strong diamond guild can take an entire map in 15-20 minutes. Yes, it requires diamonds, but people share the load so no one has to buy diamonds with RL money.
Exactly - when GBG went live in November 2019, there was a short learning curve and progression through the GBG ages (Copper, Silver, etc..), and then a game of
season opening speed chess in Platinum/Diamond that was amazing to be a part of.
A GUILD FLIGHT CONTROLLER watched the map, and redirected their assembled people power to block, or allow traffic on sectors based on using GBG visual clues (bullseye or pointy arrows at the time).
We were consummating new sectors in < 1 minute, sometimes the advancement count would jump by 5-10 advancements/second (it was choppy visually, but it really did fly up to 160...). SO yes - 15-20 minutes of time was really all it took to own it - and define season terms to others.
