I disagree with this, as firstly it’s a community event. Of course everyone who participates is going to get rewarded with the same thing you are.While it will be nice to own the Grand Psijic Villa it will be so common that investing in decorating it won't be worth it.
Same for the mount and pet, if I see the mount and pet anywhere I go it won't be special.
There needs to be a level of exclusivity for the in-game feature so it will be worth having and when hundreds of thousands of players will use the same in-game items at the same time it greatly devalues their worth.
