You could always ask Kyd on Twitter why he doesn't score AC anymore, but the answers are obvious: either he wanted to move on or the developers wanted someone else. I mean I was once upset Alan Silvestri didn't score Winter Soldier or Age of Ultron, but now I realise his music might've fitted the first couple of Captain America movies but he wouldn't fit their follow-ups.
