I submitted a support ticket. Got a positive response from Riot that Fantasy LCS is coming back

This was my support ticket:

There are over a dozen posts on the leagueoflegends forums in both the E-sports forum and the Fantasy LCS forum asking when Fantasy LCS is going to be updated. The spring split is starting on Thursday and not a single one of these posts have been responded to nor has the Fantasy LCS website been updated. When are we going to get an update on Fantasy LCS?

And please don't tell me to go post this topic on the forums. I already have, along with many other people, and no one has responded so obviously the forums are not a adequate solution to this problem.

This was Riot's response:

Greetings player,

Thanks for writing in! I can't provide a specific time frame for when Fantasy LCS will be online but the team is working hard to bring it back. Keep an eye on our website for the official announcement.

So it sound like they had some difficulties getting everything updated but that it will be back. Hopefully they can work out all the issues before week 1.
