Well I've only used a DE a few weeks and have only tried the one I have which is a Muhle. I haven't had a problem with it yet. I have also been using mild to medium aggressive blades based on what I've read. But after reading quite a bit about them it could be that you just have an aggressive razor and/or blade. There are mild blades such as Derby. Have you tried different blades?
Also, light to no pressure on the DE same as straights. Don't press down like a cartridge. I have found that I can even shave right over a raised mole with it with no problems. I used to nick that mole every couple of months with a cartridge.
One tip I saw somewhere said to hold it down near the end of the handle with the thumb and two fingers to lessen the likelyhood of applying pressure. May have been Mantic on his shave site, not sure.
