I've noticed a very simple way of dealing with monsters that can kill me outright in one hit: Box them in with blocks. They are completely at my mercy since I can hit them through the blocks, but they can't. I think a legendary item having this characteristic is a great idea; at the same time, having EVERY SINGLE weapon able to do this makes the game rather easy to manipulate into getting easy loot. A particular example was that I went to a level 25 planet after just getting to sector Gamma, (with a level 18 weapon, used to kill a certain boxed in boss), found a pirate ship, and boxed them all in, killing everyone on board (except the quartermaster, who sold me a neat gun). Another thing I noticed is that NPCs outside of the boxed in area do not react to this, and since the back wall is not necessarily closed off, they should be able to see what is happening inside when it isn't. While this is a great way for advancing through the beta, I would recommend changing this before the official release.
