"Those who climb to Gold in both Solo/Duo Queue and the Flex Queue will unlock an extra-special end-of-season reward."
2017 season rewards announced, nothing.

Anonagon3 votesyou get a chroma for graves for each queue you get gold in
Victorious Graves, granted for finishing the season at Gold or above, comes with additional chromas depending on which queue you levelled up in
did you even read it?

EndlessSorcerer1 votesIt seems like they didn't forget; they just decided to lower the requirements.
Climb to Silver in more than one ranked queue to get your hands on 2017’s Victorious ward skin
We’re repealing and replacing the requirements for the Victorious ward and opening it up to folks who want to crush in multiple queues. While Victorious Graves is still locked at Gold, we wanted to spread rewards out to encourage your Silver V mid laner to actually use these things (for once).
Mysticman891 votesYeah, it looks like they eased back on the requirements for that to only be silver in both, netting the victorious ward.
Their initial statement is technically still accurate, since if you do climb to gold in both you'll get it, but it's unfortunate for those who would've prefered to stop at silver.
That said, there is a a chroma for each queue you get gold+ in, so it's not like going the extra mile in flex (or 3v3) didn't net you anything extra.
