number of seasons left?
I guess that season 3 (which starts today) and season 4. Each season last ~2 months and after each one is a month of rest, which means 4 seasons x year.
It’s probably still worth doing what you can. I linked a post at the end. If you go to second page of replies there’s a Dev post. The next paragraph is quoted from what he wrote.
“If you can’t/don’t get the legendary if a specific year then there will be another way to obtain that specific backpack. I can’t go into any details on that, but you WILL be able to get previous years backpacks in some way.”
This next statement is my opinion/theory: So assuming that this other method actually gets implemented. Logic would dictate that it would piggyback off the original rewards.
