I'm on xbox one. I get dropped whilst doing anything, patrols, bounties, tower, but the worst is strikes, perhaps 5% of the time I actually make it past the loading spaceship screen and somehow make it into the strike itself then on rare occasions I'll be able to last the whole strike. I often get dropped between zones, for example, carrying out a patrol mission which requires me to scout an area, I'll try and cross the map and in certain places (which are the same areas every time) I'll get a loading symbol in the screen whilst my character stops moving, then after a few seconds I'm usually dropped. The only time I don't seem to be dropped is when playing solo missions, when I'm in my own zone with no other players. It appears to me the server drops seem to occur when I'm either queuing or playing in a zone with other players present. But the strike queue is by far the worst.
