Poor selection of data discs in conquest

I am also in Normal mode, and... for some reason... I am faced with the opposite problem.  I have too many GREAT data disks... and not enough slots.  Given that we have seemingly different data disks, I see two main things.  Either, it is completely randomized... or you are not doing the Golden Path (I forget what it is called).  If you are only doing the Golden Path, you should be getting better data disks... I don't know, though.  I am sad to hear you are facing a much different story.

I was initially wondering “Why is someone with 11M GP doing normal mode in Conquest?”, but then I saw who was posting. 

Your post is extremely vague. You haven’t used the name of any of the disks you have found or not found in conquest. The disks do change from one conquest season to the next, but the same disks are available for all players. I often see people saying “I’ve had terrible luck with data disks”, but it’s rare that people saying this can identify which disks they are missing. 

Do you follow the challenge path (that’s the different coloured nodes in each sector) that leads to having two different Data disk nodes to choose from when you reach them? 

btw the number of dots on a data disk does not dictate its power, caustic emissions is powerful, zealous ambition is overpowered

Also, at least for this Conquest, "Booming Voice" was surprisingly easy to get... and, paired with "Perseverance," any team is basically unbeatable.  I like to add on caustic emissions, though, as it works well with my Great Mothers Nightsister team.  GreenSunRedMoon is right, even lower dot data disks are powerful... if you use them properly.
