First three things devs would change if they played the game for a single day?

1. Races. Rewards, times, types, length, etc... Great idea, not very good execution the last couple seasons.

2. Strongboxes. Great idea. Awful implementation mechanically. "Let me just spawnw 30 mobs around me and freeze my client". Yes, smoke mine/warp/quartz/etc. They shouldn't be as necessary as they are.

3. Uneven progression balance. The worst offenders are A3X vs act1/2 of next diff, corrupted area bosses, devourers, certain exiles way overturned comparatively (hi magnus).
