People complain about playing almost a year and having any or few unique item.
I have a simple and fair solution. Can you consider a unique item quest.
If you open
50 titan chest, complete the quest phase 1 and get a random unique.
150 titan chest, complete quest phase 2 and get a unique.
300 titan chest, complete quest phase 3 and get the last unique.
Phase 1 looks to be achieved something like 1-2 month for active players.
Phase 2 something like 3-4 months
Phase 3 something like 6-8 months.
Active but unlucky players get the uniques by this way… And be more happy…
