Uh......no? I'm sorry, but you are horribly misinformed.
Deathfire Grasp was removed because Riot couldn't figure out how to make it not a problem without making it an entirely different item. So, it was easier to just remove it.
Revive was removed because it had be at such a low power level, that it was essentially useless. Remember the first time URF was released? EVERYONE was running Tele and Revive. That gives you a good representation of what would happen if Revive could have competed with the other summoner spells.
Atma's Impaler was removed because Garen was the only champ who would ever build it. If they were to buff it to a point that other champs would use it, they would have had to nerf Garen into the ground and make it to where he either solely relied on it, or was completely useless.
Executioner's Calling was initially removed for the same reason why Atma's Was removed.......no one built it. It was either uff the item to God Tier levels, or remove it. However, unlike Atma's, they brought it back completely reworked, since AD did not have any option for Grevious Wounds.
All of these weren't removed just because they were a problem, they were removed because Riot couldn't properly fix the problem they were presenting. In each case, it was easier to remove them because if Riot tried to fix the problem, they may have created 10 more problems in the process.
