1) Loving the equalisation of damage and going to 13% on r10 from 15% - could go lower, power creep has been significant and continues to increase
2) The quest/raid reaper damage adjustment seems backwards to me. Low reaper raids were a colossal jump in difficulty to a lot of people - think low dps raids not being able to go from LH Den of Vipers to R1 Den of Vipers, while being able to complete R10 questing, or even older raids on maybe R5-R8 like Baba or Strahd. It is not the high reaper raids that needed to be easier, if anything low reaper raids needed to be ever so slightly easier and high reaper as hard as currently but less focused on stacking the best dps builds.
A better way to achieve that would be to add group utility to underperforming classes (debuffs like Warlocks Soul Eater capstone having higher uptime, adding similar but less powerful to other trees, adding abilities like For Cormyr to non-racial grouping/support oriented trees that also help casters, not martial restricted) - stuff like that. The casuals and generic pug raid groups that struggle because they don't run meta builds are the ones that need help more than the minmaxers, this does the opposite.
This will keep low reaper raiding in a bunch of raids inaccessible, while making the nolife tryhard raiders have less challenge - the opposite of what should be the goal I'd imagine? I can not see this raid adjustment as a good change no matter how I look at it.

High reaper really could include more interesting things for us to figure out and deal with in general. Horrid does negative now so vengeance reapers are less scary - probably a good change? Cyclo blasts are less stupid, good change. But they do make reaper easier.
The DR change might reduce available player damage for less prepared or fleshed out builds, and some popular meta builds that steamrolled are less able to do it (Dragon Lords and crossbows) but other builds that steamrolled it will do it even harder than before since we have more enhancement points available, attacks that aren't animation cancelled are better and DS uncapped so many builds that could cover DR breaks look to be a lot stronger than before and will just steamroll even harder... A lot harder in fact. Unsure about casters.
It'll be hard to gauge the impact of all these changes since there are so many, but I think there will be need for another perhaps larger reaper adjustment later.
