What’s the one thing you don’t like doing in warframe?

With warframe having so much to do there will always be something you don’t like to do. What is the one thing you don’t like or didn’t like and won’t go back too? Could be a general thing or something specific. If I had to pick one thing I just don’t like doing it would be anything with the railjack. I’m just am not a fan of the railjack stuff.
