Your argument is a bit flawed. That's like saying you shouldn't play bait with Flash or Exhaust, or shouldn't use Cleanse prematurely for the CC reduction, or shouldn't wait for allies to be hurt before using Heal. All spells have variance in their usage, even the binary ones. There are penalties to getting yourself killed intentionally. They are not always immediate and are often ignored, which is the fault of the player.
Removing Revive and doing nothing about Garrison would make only about 20 champions viable in Dominion. 3 supports 1 aoe cc and 10 Garrisons, with double Maokais in bot lane every game. Pushing would be wrong, skirmishing would be wrong, and killing would be pointless, if even possible. First team to win the windmill fight would hold 3-2 for 10 minutes or more. Revive is basically what keeps the turtle-fest meta at bay.
Revive is probably going to drop the speed boost in S3 anyways due to the new boots, and the hp boost will probably become the new spec.

situation as Karthus where you actually want
to die is in a team fight when you're completely out of mana, low on health, W is close to coming off CD and 1 or 2 enemies might escape the fight with very little health. Of course, you were probably joking.
