I like rushing strikes. It keeps interesting how fast I can complete. On nexus once you kill the three servitors all you have to do is literally run to boss and kill him with out touching any adds. For archon priest run straight to locked door clear adds open door run to boss. Valus one guy does first ghost part rest run to three guards. Ram guards with interceptors take out tank hop on legendary sparrow since faster than interceptor go to boss. Moon strike rush to door open rush to boss and smack damage and kill before second drop ship. Earth strike is the only one hard to rush.
