I moved it to achievements section, maybe there’s players with similar ideas here.
Xanlorash, I think the X amount of mount achievements have a big issue with response from Devs about new players, check MrGm interview, maybe looking back to why players have few mounts, like Alt armies required to beat odds with a lot of RNG mounts, bad luck mechanics, maybe new achievements as mentioned on this post…etc, new ways to involve players in collecting, also Devs could bring more achievements for 450-500-550-600…etc eventually or now but improving on mount collecting overall.
