It's been just over a week of the season, give it time as i'll assume there is a bit more to come. While yes, this is starting slower than Dawn did, I doubt they cut content.
We're trying to be careful with roadmaps, leaving players to discover more content on their own, and this is an expected side effect. Definitely seeing the feedback that the season started slow, but there is indeed more coming.
Moon bunker kicks off next Tuesday, which will bring some different upgrades, another Seraph weapon, and more Heroic Lost Sectors to the fold. While some of you may have already taken a peek, Trials has more weapons and armor that will come into play over the next few weekends. Grandmaster comes in mid season, with Guardian Games and such as well.
We hope that as more seasonal content comes live, players have some positive feedback. We're still in here every day though, collecting your thoughts.
