I don't think the game changes for a certain number of players if you're running a strike or anything, but nice work sticking it out. I used to be abandoned all the time in high level strikes, but if you keep going and tough it out, it's really worth it in the end. If it ever happens to you again, try thinking of it as a training exercise and work on honing your skills, both in terms of accuracy and survival. You can never have too much practice, especially if you're preparing to jump into the raids. Be ready to hold way more than just your own.
