The logic here is astounding. If the development team's opinion was "whelp, shouldn't have died in the first place!" then they wouldn't have implemented a trait for healers to allow combat raises. No one is asking for a "get out of jail free card", they're asking for a little more forgiveness when you're trying to get someone up since most challenging encounters make it incredibly unpredictable when it comes time to get a safe raise off.

There's no good reason why someone should be immune to heals for nearly 3 seconds after raise, yet they can still take damage. They get a debuff and it costs a lot of mana to raise someone. What more do you want? Not only that, but you can't say that a death is 100% the fault of the person who died. How about a disconnect from the player? How about a tank lags and causes someone else to pull aggro and die before the tank can get it back?
