It does not. It is a one time usage, and yes, you can make 2 team fights 3v5 and one 4v5. Just don't forget that the enemy can also run if you do, and survive it. If they all manage to run after you killed the tank and AD carry, they wait 60 seconds at their turrets, then attack when their allies are back.

If anything, it'd make supports less useful, because it can greatly lower damage output, while, if a support would be a bruiser, the % damage output you'd kill would be less. Imo, this is actually a nice change. I don't really like the idea of a champion that can neither absorb nor deal damage, nor has great cc like some tanks (for example Nautilus, Leona, Alistar).

Also don't forget that taking it on all champions is a bad idea. For example, I net something like 2 kills per game by taking Exhaust + Ignite combo in my top lane (my top lane because I end up zoning the enemy in almost 70% of my games. Again, thanks to this combo). If I play against a Hand of Death + Flash, then I have an easy time killing you with this, even more than when you play Exhaust + Flash or Ignite + Flash. Of course, you can use Hand of Death in an attempt to get lane control. I just ask the jungler to gank, kill you with my jungler as help, and we are equal. AKA Hand of Death is useless in laning phase, only take it on jungler or support.
