Quite a few DMs ban resurrection magic or make it much more difficult than it is by RAW. It's the one thing I house-rule in every D&D game I run--I think easy resurrection makes for an absurd game world and makes PC death all but meaningless.
If you permenantly lose a point of CON when you are brought back and a lower CON means the chances of surviving the process becomes more difficult then death still has a high cost.
