Council members defending that Glad Mounts don’t have the same mechanic that Vicious mount on which once you reach a goal, you can accomplish this again and earn another reward from a pool, which is a good idea for new players, returning players and general player base, it still maintain the requirements and avoid the seasonal fomo effect for some players.
The argument is the value around that mount representation, so why they don’t mention that Blizzard already diminish that perception of value when they make Glad mounts usable by any character, basically you can pick the best classes every patch and use those to achieve glad and then use the mount in another class, I think that in a game on which the balance is not their strong for pvp, a pool of rewards could promote more pvp participation for some players during some season and if during that patch your main class is OP, you can take advantage and farm or select the cosmetic that you desire.
