It doesn't matter if being inside a dung or on the open field, i'm getting several DCs, about 1 each 8-15 minutes. Also the game won't close properly when quitting, eventually it crashes during the process...
I crashed a couple of times when I was inside Cyrodiil a couple days ago. (And bad loading screens.)
My game never crashes outside of Cyrodiil, though. I also don't have any loading screen problems outside Cyrodiil. Cyro seems to be the area with the highest numbers of issues, by far.
Crashing issues also have something to do with where you are in the world, as well. (Real world, I mean.)
If you're not in a PvP area and are crashing every 10 minutes, then it's your system and not the game.
If you are playing in PVP, don't expect any improvements, it's been like this for 2 years. ZOS either doesn't care or are unable to find anyone who has the ability to fix the issues.
