Hero's Accord (hardest queue in the game) - For your first completion every day, you get 2500 RP and 20 seals of the brave.
Random Dungeon (easiest queue in the game) - First completion 9000 AD and 90 seals
At the typical conversion ratio on the auction house, 2500 RP ~ 7500 AD, 10,000 AD at best.
I know that the daily AD rewards were moved to the lower queues to be more accessible to all players, that's fine. However, it left Hero's Accord looking abysmal in comparison.
The hardest queue in the game shouldn't reward less than the easiest queue in the game. It's just plain silly.
Hero's Accord should at the least reward the 90 regular seals that other queues do in addition to the seals of the brave. Then it also either needs its own AD reward, or a much higher RP reward.
I know it'll never happen, but running that queue could even put you in a loot table with a higher Ultimate Stone drop rate. That would make it worth running for sure.
