Many players seem to have an issue with just staying alive after Mod 16 hit. Now, I'm not talking about things like the broken Maze Engine content (where you are lvl 60, but the mobs 73-81), but regular ordinary content, in particular when playing solo.
Well, here is what to do.
First, get rid of any bad practices. You have to dodge out of red zones and pay attention to game mechanism - for example if you attempt GWD and ignore the red wolves you cannot blame anyone else for your death. Healers cannot heal stupidity.
Second, learn to play your class. You may think you do, but M16 is basically a whole new game. Expect to spend a lot of time with a training dummy before you venture out in the world.
Third, make sure your stats are decent. Having one stat at 100K and another at 20K, when both should optimally be at 60K is not a smart thing.
Fourth, Improve your offensive abilities. I am a great supporter of the "The best defense is a good offense" school of thought. A dead enemy cannot harm you, so learn how to take them down fast.
Fifth, you will get hurt, and you will need healing. Make sure your sources of healing are adequate. You might be using potions and health stones, but quite frankly, if you find you are constantly using them, you are doing something wrong. If you are in a group, a healer may be able to keep you in good shape. If so, fine. Healing companions do not seem very reliable right now. Some which used to heal for 15.000, now heal only for 150 or so. This may be intentional, or it may simply be a bug. No word yet. However, there is one important and fairly reliable source of healing: Insignia bonuses:
Barbarian's Revelry (and maybe Barbarian's Delight too), Champion's Return and Survivor's Blessing. If you pick all of those, you might not need much more to greatly improve your survival chances.
Make NWO great again, please....
