If we give a prize to every actual milestone, there will be nothing else to give.
There is limited milestones as for : 2k(hat) - 4k(Hide-out) - 6k(Limited Station : sK is the last one who will get it I suppose) - (9k wasn't even expected)
If we keep going further, there will certainly not be enough items to giveaway. IMO Ebi should try giving hours to its allies (even tho it's dying) or start having the true fun of basing (and not standing afk inside a base)
I'm not sure if there will still be other milestones, I'm not the one who decides that.
