To be honest, I do not like that Revive is sort of a "mistake eraser" and such a thing is just handed to every player.
I am a fan of the idea that Revive should be removed as a summoner spell yet remain on the Crystal Scar in another form that require more strategic planning. The idea is very similar to what they did with Zhonya's Ring. An item that was far too powerful so they split it into two still powerful items.
Revive's power is separated into three parts: the actual revive, the speed boost after reviving, and the health boost.
The alternate forms could be in a form of a buff that you can get from completing a question. The sacrifice that is made is that time is wasted trying to get this buff. If the actual revival is in a form of a buff that is rewarded after a quest then the amount of revives in a game can be controlled. Meaning only select individuals can get it. Unfortunately, at lower elos, people will probably screw up and the person who needs the revival the least will probably take it. At higher elo, people should be able to determine who should take it to give their team the biggest strategic advantage.
For Season 3, Riot made Boot Enchantments. Homeguard was disabled on Dominion for obvious reasons, but why can't Riot play with this idea more? Make an enchantment that offers a speed boost when you respawn. In a map like Dominion where death is common, having such an enchantment is useful, however, in order to use it, you have to die. So, it is somewhat bittersweet.
Riot could also give the powers of revival in an item form, like a Guardian Angel that has been edited for Dominion. The item's active can only be used when dead. People would have to make a decision "Is it worth it? If I get 'FDru's Angel,' I have to waste a ton of gold on this item that'll probably only give me one 'do-over.' I also have to give up having a stat-heavy item for this item that is expensive due to its utility, not for its stats." My idea is to make it so organized teams will still buy this item, but only selected individuals would get it. Who would get this it? How can people make it so the person with this item cannot simply be ignored?
As for those who argue that people would have the ability to get a combo of summoner spells that could result in something more unfair than having Revive, that's something RiotNome has to tackle. I don't think RiotNome is as limited by saying "I can get rid of revive, but they'll take a more anti-fun combo of summoner spells." I think RiotNome should be saying "Let's change the summoner spells for Dominion to make each spell offer a variety of strategic play." Someone from Riot, a developer I believe, even said that he suggested to RiotNome that he should just make Dominion specific summoner spells instead of using Summoner's Rift's. He said that RiotNome seemed against the idea but I think that just revamping Dominion's Summoner's spell might fix a ton of problems and give RiotNome a TON of flexibility.
dr;tl: Revive in its current form limits strategic plays. RiotNome could probably figure a couple of ways to "keep" revive in the game but open up a new field of strategic play with it.
Edit: I mean, yeah, FDru is known to be very blunt. But if you think about it, there is some truth to what he says. If you sit down and wrote it down, is Revive in its current form "anti-fun?" Is it the best for Dominion right now or can it become even better? If it could be better, wouldn't you think that changing it for the better would make Dominion an even better map? Remember that we are not simply trying to convince other players to play Dominion. We are also trying to convince Riot that the Crystal Scar is a map worth pouring resources into. A map that could see very competitive play. If we limit ourselves to keeping the status quo, Dominion cannot become this incredibly amazing map in Riot's eyes.
