The recent changes to the reward system have made it impossible to earn high-tier rewards (A, A+) without facing an unreasonably high difficulty level. The system now requires a massive Power Level deficit that makes the activity practically unplayable, especially for solo players. **Problem Description:** With my Power Level at 400, I am required to set the difficulty to +60 to achieve higher-tier rewards (e.g., Tier 4). This means I am fighting enemies at Power Level 460. The enemies have so much health that it takes me 10+ shots to defeat a basic red-bar enemy. This isn't a challenge; it's a grind that is far too difficult to complete. In the past, players could earn higher rewards by completing a side quest and getting a B+ rank, which would upgrade to an A rank. Now, a B+ rank only gives B+ rewards, regardless of how well you perform or how many side quests you complete. This fundamentally breaks the reward progression. **Expected Behavior:** The difficulty scaling should allow for an achievable, but challenging, progression. Reaching the highest rewards should require skill and a little grind, but not an insurmountable Power Level difference. There should be a way to earn an A+ rank with a reasonable difficulty setting (e.g., +20 or +30) by performing well in the activity and completing bonus objectives.
