You can still get decent amount of materials, Mirror Maiden shard and UR Murakumo (maybe mirror depending on how many points people get).

It's possible that this LR / GUR gets reissued in future like Inspired Relena did (you could buy it from ABB rewards) so it isn't a waste to get halfway done with it.
