What about Dinah? She killed the guy she believed killed Vigilante the first time in cold blood without even thinking about it and Laurel's not gonna get a pass just because she looks like Quentin's dead daughter so unless she dies too Laurel can't stay. I also just don't think there's enough for Laurel to work with in Arrow since Olicity's not going anywhere, Dinah, Curtis and Rene will never trust her, Diggle and Felicity can barely look at her, and I heard a rumor that Thea and Quentin may be exiting this year. At least in Legends she has Sara.

As for Wally well Hawkman was a series regular and look what happened to him. I read an interview with Brandon Routh a while back where he said "Wally will join the Legends, at least for a while" so that indicated to me that he's only temporary. Personally I think they've just sent him there because they don't know what to do with him in Flash at the moment.
