The main reaosn this idea fails is because the idea of being instantly killed through no fault of your own isn't fun.

If you die, it's because you made a mistake. Either you allowed yourself a poor matchup, you didn't check/ward the immediate jungle to spot a gank, or you were caught to far out in a team fight. In any case, you die because you made a mistake.

That's what makes a game fun. Your success and failure is based on your skill. Even if hand of death doesn't lead to your team losing the match, any consistently good carry can expect to be killed once or twice a match through no fault of their own. That's simply NOT FUN.

P.S. Exhaust+ignite; countered by heal, flash, cleanse, playing a tank, playing a hero with tenacity, laning with someone with a taunt, etc.
