v118 - Champions Update Notes

No more invinc. upon revive? and you can chage gallant as much as you want within the time of the event?

You can only charge 10 Gallant Emblems max per entry, after that, you cannot gain any more emblems unless you leave and go back in. You can do this as much as you want during the time PvP is open. Last I heard, you could charge while afk.

Also, while there's only one map, there's many, many instances of it, and depending on how well you do, you'll be moved to a different instance with players closer to your skill level.
