Legacy league does not end tomorrow, not sure where you heard that. And it is in fact part of the base game, however it's instead called "Zana mods." I know many people are already annoyed with all the micro managing of game mechanics just to run a map, and leaguestones are the worst. I've seen many ways proposed to make them better (increase charges to 10+, make them all a steady 5 charges, etc.) however I think Zana mods work just fine. It's a system already in place to run previous mechanics, it might just need a slight rework to keep mods on par with one another.Legacy scheduled to end tomorrow 2200 GMT. Too bad, it's been my favorite league by a huge margin. They should make legacy a permanent part of standard league.
