I am going to give my opinion on these three. Don't take them negatively.
Yes, there should be new weapons occasionally, yet over time that sets a wall there. The wall of old items being out of date, player inventory limit, to another huge change. I'm not getting into details there, but there can be other things that can replace this.
I doubt they would do this. I play another game that does not give drop rates. It just lets you know what you can get in a pack. That is another idea that Alex could add. Epic Weapon pack, leg pack torso pack that cost tokens.
Yea, that ended in February, I believe. He could just do an old weapon Hunt portal. Do it one day weekly. Like a "NEMO" portal for once a week. If Alex did this, then it benefit in getting rid of silver boxes.
