The following bugs I would consider high-ish priority and are (to the best of my knowledge) still issues, feel free to cherry pick them to your hearts content:
2466
3358
3415
3617
3618
3680
3682
4180
5073, 5357
5454 (nerf packages!)
These bugs are high-ish priority, but easy to fix, but I cannot verify because they are location specific:
3360
3361
3362
4201
These bugs can be closed as you've already fixed them:
2316, 2354, 2831, 2874, 2875, 2876, 2895, 2911, 3065, 3290, 3350, 3354, 3357, 3529, 3722, 4551, 5600, and 3153 (not a bug), 3687 (not a bug)
