IIRC, WOTR Sealed comes up in the rotation as previous Sealed leagues finish. Assuming each Sealed league takes a month, and there's five Sealed options (FOTR, TTT, ROTK, custom, WOTR), you can reasonably expect a WOTR Sealed league every five months.
That is assuming a regular preset rotation. Based on...
Maybe its time to go Expanded My Cards.
...it seems to me that there is no preset rotation, it's just sorta whatever Eukalyptus feels like it's time to do.
My issue as far as the constructed leagues go, is it seems like players for most of the other formats get a full month of playtime in their favorite, while Expanded players only get about a week. Also, since most of the other formats have a version of Sealed, players of other formats get to see their favorite come up in rotation at least 33% more often, in the form of a Sealed League. Expanded only gets a week of All Cards, and occasionally a week of My Cards (which frankly I'm not a big fan of, for the same reasons Euk has).
And I am distinctly remembering that we did have a multi-series Expanded League, because I can still see my competitive stats for the final Open Format series. We should do that again!
ETA: Also, I feel like many players (myself included) get really burned out on these looooooong Sealed Leagues. Do we really need 4 series of those? Or really even 3? How about a single series, where you can pick from any of the starters in the block, and get maybe 4 boosters from each expansion?
I'd like to see a Hunters sealed league too, for the record.
Dang right. But since it sounds like that's something MarcinS would have to code, I guess we're probably not going to get it. I still can't believe he didn't add the Hunters Starters during the reset. I know he's been provided those lists multiple times by moderators, myself, and other players.
