-Eggs seems pointless to me, nothing special about them except that they can't be synced which is one of the rewarding feature of bosses. I would suggest boss pokemon rewards to remain syncable. Some people don't like to hunt for hours and just try their luck at bosses to get synced pokemon and some pokemon are exclusive to bosses so no way to get them synced doesn't seem good to me.
-Hard mode rewards seem low considering the difficulty, 60% chance to still get t1 (berries after hardwork, nice troll) is pretty high imo. And low money reward tbh, all purpose of doing bosses would be gone.
