My only advice, switch it up. I have all 3 classes. So I'd go in as a Titan one day, next day Warlock, next day Hunter. Would give myself a number. Like I'm only gonna run 5-10 strikes right now, and I moved on till the next day. Also Spotify. Would listen to music and not even think about it. It will eventually drop. I noticed that some days no legendaries would drop at all. And other days after every strike someone would get a legendary. It's probably superstition, but if you start seeing legendaries drop a lot, stay. Don't leave. Keep playing.
