I predict Riot will bring back Revive.

So with the new rune, Summoner Specialist, just announced recently it made me think of a retired summoner spell that would be perfect for it; revive. Revive would be worthless to have for the entire game, but if you could swap to it in an emergency with Summoner Specialist it could become the BEST SUMMONER SPELL. Honestly, I kinda feel like Riot made this rune based on the idea of making revive valuable.

This would become a HARD META STRATEGY that would change the entire game (if at the very least make every game much longer). Now either Riot will bring revive back on their own, or the LoL community will beg to have them bring it back. Either way, I called it.
