It's about player trust. Sticking to one's word. Not changing it in midnight without prior notice out of the blue. I wonder if you'd react the same if they started dropping good TWEN weapons every day until end of twen, oversupplying the market of good items even further, good luck selling a good weapon for pure ped then, as I'm sure you're already experiencing difficulties with it.
Since Summer Mayhem is gone, and that was the reason the summer strongboxes were phased out, why couldn't they've just done "Migration strongboxes" instead of sticking with same Summer Strongboxes? It would've been so easy for them to do that.
At the very least they should update these Summer Strongboxes to drop Summer Ring 2023 with new stats.
Btw there's already 173 summer ring 2020 out there. Migration gonna last for like 60 days more. Can you imagine how many more more Summer Ring 2020 there'll be by then, if they don't add Summer Ring 2023?
