During EA - it's possible that "save wipes" will occur a few more times. If you don't want to restart - it would be better to wait for a full release.
I was able to do 2 full playthroughs (around 60 hours) and I did a hard stop. There was not much I could do in EA.

This time I plan to do 1 full detailed playthrough and stop again - there is no need to spend like 200hours in a single patch in EA - there it will be a lot of changes.
