Do not buy tier 4 lockboxes! Buy tier 3 instead!
Tier 4 Lockbox - 64 keys - rewards 4 random items of at least uncommon rarity.
Tier 3 lockbox - cost 24 keys - rewards 3 random items of at least uncommon rarity.
At the cost of 48 keys you get 6 chances at loot, and at the cost of 64 keys you get 4 chances at loot?
After experimenting at trying them out myself I found absolutely NO difference between the quality of items found in the tier 4 lockboxes and the tier 3 lockboxes.
Bought 5 Tier 4 lockboxes and 5 tier three lockboxes. Same average quality of items, EXCEPT the tier three lockboxes reward FAR FAR more loot!
In fact someone else running this same experiment got their first legendary item from, you guessed it a TIER 3 LOCKBOX and NOT from a tier 4 lockbox!
I REPEAT TIER THREE LOCKBOXES REWARD LEGENDARIES SO WHAT IS THE POINT IN WASTING METRIC SHTAKO TONS OF KEYS ON TIER 4's?!?!?!?!?!?!?!?
How in the name of the golden diapered baby jeebus did this make it through alpha and beta testing?!?!?!?
Is this working as intended in an attempt to encourage people to dump cash into the game to buy keys to purchase more boxes or has it just been bypassed for the past year of testing?
The only crafting system, and the main way to get the best loot is broken? Through Alpha AND through beta?
This is 100% completely unacceptable in any way shape or form.
This needs serious attention urgently!
And reading the tooltips on the boxes it mentions NOTHING absolutely NOTHING about having higher chances of better gear through the more expensive boxes.
TL;DR Buy tier three lockboxes, collect legionaries ???? profit.
