I'm going to split my post into two parts. First is the loot experience when it comes to the campaign and second, is the loot experience when it comes to maps/end-game (I've ran up to T6 maps for the time being).
~CAMPAIGN EXPERIENCE~
My feelings in regards to the loot drops through the campaign have been positive, for the most part. I had one particular anomaly through the beginning of my character's campaign.
For instance, I started an
SSF Huntress in 0.2 and prior to
Freythorn (Act I), I've had
one Exalted Orb drop (alongside some Rare Gear from bosses).
Once I got to
Freythorn however, I had
4 Exalted Orbs drop (4, I kid you not) in a
SINGLE INSTANCE of that particular zone before killing the boss of the area. This hasn't even happened in any of the maps I've ran so far in the end-game.
Rest of the campaign, I had the occasional Exalted Orbs drop, some Regals here and there, maybe an Alchemy or two, nothing too crazy or too little. I could somewhat comfortably change gear if I got into a situation where I struggled.
What I really struggled with however, was getting a good weapon upgrade in Act 3 Cruel to give me some much needed damage boost.
Other than that particular instance however, through
salvaging,
disenchanting rare drops and maybe gambling for rings/amulets (very rarely), I could easily upgrade my gear. Whether that was fully upgrading a white base item all the way to rare through all the currency OR straight up purchasing items through vendors.
Sure, there were maybe a few fail slams/rolls on some of the items but nonetheless, I didn't really struggle with the loot OTHER than getting a good weapon in Act 3 Cruel.
Maybe a very minor boost to Exalted Orbs, alongside Regals could potentially help? As a failsafe measure mostly for scenarios where you might roll Light Radius with that Exalted Orb/Regal you just slammed into your gear.
Anyways, overall, my personal loot experience through the campaign has been fine. I didn't even go out of my way to intentionally full-clear or explore the zones/maps for more loot.
~MAPS - ENDGAME EXPERIENCE (UP TO T6 SO FAR)~
First few maps that I ran (Blue T1s/T2s/T3s with the occasional Rare 4-5 Modifiers) have been a little bit on the underwhelming side of things when it comes to loot. On average, I'd drop one Exalted Orb per map.
Lots of rare items, lots of Uniques as well (compared to 0.1), so at the very least, I can easily Regal a bunch of White Bases should they hit good modifiers with Transmutes/Augmentations.
In terms of
Increase to Rarity, I'm running with around
~20% Increase to Rarity, alongside a Rarity Increase charm.
I haven't seen a single Divine Orb yet in maps. (oddly enough, I dropped my first Divine Orb in Act 3 Cruel)
What I'm
really lacking though, are
Vaal Orbs. It feels like their drop rate is gutted compared to 0.1. Which is a shame since I want to use them on the Essences and well... I've used them all up. I think I've had 6-7 Vaals drop in total since Act 1 all the way to T6 Maps.
Also, I will also mention that Expedition drop rates seem indeed kinda buffed. I've had quite a few generous currency drops of Exalted Orbs/Chaos/Alchemy thanks to Expeditions.
This is my currency stash so far. (I've been slamming Exalts on anything that I consider upgrade-worthy)
So... Yeah. This has been my experience so far. At the very least, I know that I will stumble upon Exalted Orbs to keep on potentially crafting more items and progress further so it's not as bad in my opinion as some people make it out to be.
Then again, I just got to running T6s with low rarity increases so far, so I don't know how things are on the higher-end of the maps. No Ring of Pilfering to keep an accurate track of the drops but I can somewhat gauge on average how much I'm dropping.
MINOR EDIT:
This is all the uniques I've dropped since the beginning of this character.
