Hey Guys,
After playing PvE online and private for many hours, playing every mission at least 8 times on solo Normal and 5 player normal.
These are the overall rewards of these missions.
It could benefit you if you want to find drop rate or easiest mission to farm etcetera.
Im still trying to get more information on difference in drop rate between normal/hardcore/advanced.
For now, normal seems to drop more loot, but advanced seems to drop higher rated (epic) loot.
Hardcore grants not a single bonus to drop rate or xp or credits…
(Extra edit: Yes i know some of the gear drops add up exactly to a round number, but im no expert in Excel so im not entirely sure how it decides how many decimals are used… im sorry for that…)
Every mission has been completed anywhere between 8 - 16 times to get results.
Algorithm the most times, heliophage the least.
Here are the differences between Story mode difficulties:
Number of plays on Normal = 72
Number of plays on Normal/Hardcore = 48
Number of plays on Advanced = 51
Advanced hardcore is a tad to difficult to get a good list of stats just yet.
Will try and upload once i get more stats going.
Hope this helps,
Cya
