First, thank you for the update. It's always good to hear (imo) what's actually going on, even if it's not necessarily what I was hoping for.
Second, I will echo @Atlas's statement that this is disappointing. The new method of progression was teased a month and a half ago, back on June 14th. Just 8 days ago, Hannah said that it wasn't ready, but didn't express that the whole concept had been scrapped.
As someone who has played this game for 665 days and was dying for something new to do, it's really very hard to view this without being quite depressed about the direction of the game. My play time and interest in the game has been slowly waning over the past months and in my head I kept thinking, "Just wait to see what the new progression plan is, maybe that will breathe some life into the game for you and reignite your interest!"
Instead, nothing new. Just the same mindless grind I've been making for the past however many months. What was the last new thing introduced to DS? Guild War back in 2.1, in March of 2016? 17 months of the same thing?!?
Ugh, I just. I just don't know anymore.
Still though, thank you for sharing this news.
edit: Forgot about runes. Runes were in 2.2, which was in April 2016.
edit2: I would rather just have a new promotion color. I don't care if it doesn't come with a skill. I never would have expected it to.
