I was part of my alliance for the whole gifting event and much more and then randomly I get kicked. I put up a lot of points for the event do I still get alliance rank rewards.
You can maybe message kabam and say you were unfairly kicked if you can give them the alliance you were in. I had someone in my old alliance that was accidently kicked out (The wrong person was kicked). So they messaged kabam and so did the leader of the alliance and in the end they got their end of season AW rewards.But, if you weren't unfairly kicked, you won't get alliance rewards, just your own solo rewards.
