No, 10 is fine because people will lag the server dieing all the time. Well, mabey 20 or 30, that way other people can cast ressurection and bring you back to life.
Anyway, even if that idea isn't used, this could be a good one:
When you die, you fall back, your dead. You will be warped away to the last safe point in 20 or so seconds. In that amount of time you can be ressurected... Almost like using a Fenix Down in FF games.
