Missing or forgeting one line in the online-event-description? Guess what? DIE!
Ride or die Legion-Block should be claimable from any Interactive or Heroic world of the same type per server, when eligible to be claimed.
No ingame notice from participation rewards that the Legion-block is excluded from challengers world and for that matter, no alternate reward is offered.
