The gold reward for range from 500 down to 1001-2500 is 200gold, the other pvp events have gold for just being in Div 1, is this a bug?
No, its just the type of brawl. All the Faction v Faction based brawls use the same system that this one used, where only top 5000 players get a gold reward. However, other PvP events, such as the “two featured heroes” and Faction Mastery PvP events give rewards to all Div. 1s. So it isn’t a bug, its just the game mode.
