I'm sorry, but I cannot associate "prestige" with obsessively farming and camping 3 days for a mount. I think "Wow that person is obsessed with being first. Good for them!" when I saw Ixion for the first time 2 weeks after Stormblood launched.
This change is good so you only have to catch Ixion 2-4 times in order to get the mount. I kinda wish they gave 1 horn for bronze though.
