Why do Seasonal Events get stripped down each year and not added too?

[Imora]

I'd guess you're new? This has unfortnately happened for years and will not change.
It's a double edge sword. Either you keep the stuff exclusive and not accessable for new players or put it in the cash shop 1+ year later the event and people never has to feel FOMO.

Google Translate is a option i guess if you really want to vent your frustrations.

Wows events have the old rewards available in addition to any new ones they may have added. It's part of why I don't do their events anymore. Didn't get that toy four years ago? It's still in game just get it next time the event is around.

Putting it in mogstation is a little nickel and dimey.
