Haven’t noticed a reduction in emblems personally. Offers or no offers.
Mats from titan loot is and always has been random, no change there either from what i can tell.
Higher grades can get you more loot, but not always better and that has been the same song and dance for over 2 years
Numbers game as far as A+, A, B, C goes
You’ll see more people with B or C grades get mats than A+ or even A
Why?
Because more people get those grades, therefore there’s more chances for the few to “i got a tabbard”, “i got a tome”, “i got blah blah”, rather than the 1 A+ guy
I’ve had 4* mats in every grade except D because I’ve never had D unless it was reduced.
Anyways mats can land in every grade, instead of focusing on trying to streak A+ scores, focus on just killin the dam titan while still hitting at least C, preferably B, and expensing as little as possible in items to do so. Just what i would do.
Back to emblems. It hasn’t exactly been raining emblems since they released. So it’s not that they’ve decreased, it’s that the amounts were always small. In fact we’re seeing more guaranteed emblems per month now than we ever have due to the revamped challenge events.
You get 2 class trials per week, a rare titan roughly every 10 days(between 7 and 12 basically, escapes can make it longer), and an elemental chest roughly every 50 wanted chests filled. You get emblems from all 3 tiers of monthly challenge events, would suggest at least completing all 3. And you get emblems from tourney loot so would advise in at least participating in every single one. These tidbits should maximize your emblem income.
