Lockbox description incorrect?
So I've been looking at the different Tiers of Lockboxes and something doesn't make sense.
The description for all (Tier 2, 3 and 4) lockboxes is that they contain at least uncommon items. There is no reference to higher chances for better quality in any particular lockbox.
What reason is there to buy a Tier 4 lockbox at 64 keys when I can buy 8 Tier 2's for the same number of keys (obviously cost more scrit) and get 16 items rather than 4?
Is there a hidden property that is not being communicated in the item description of lockboxes that higher Tiers have much higher chance for better quality?
