This is my tierlist about Ranked Conquest based on what I have played so far. There are a lot of gods that I haven't barely played against for some reason, but I do think they're really strong (Susano for instance).
*Scylla is with no discusion the best mage in the game along with Pers. Scylla is not S+ bc she got played in SPL, she is S+ right now because she used to have one of the worst early clear/kill potential in the game since she is a god made for late game, but now with the meta changes (conduit gem + starting lvl 1 at red) she has one of the best earlies and still one of the best lates, not to mention that she is also really safe.
*The nerfs to thorns did hurt a lot some gods (Cthulu, Hades specially) but they're still okay because they also got buffed with items like Warrior's Axe and Warding Sigil Upgrades. Still, you're forced to get thorns with these kind of gods since they get too much use from it and not any other relic is really that much better (You can get sunder/frenzy/ankh/horrific, but these are not better than thorns for these gods, sunder is single target and can be easily missed, frenzy is okay but adcs can outbox you in your ult with lifesteal and crit and kill you, ankh and horrific are solid options but I still prefer thorns because of the 50% healing lifesteal reduced on top of the dmg that you are reflecting them)
*Jorm, however, it's bugged with Warrior's/Sundering Axe, by fixing Deathtoll's passive to not proc with his breath, now he can't proc Warrior's/Sundering Axe either unless you hit them with an ability. I mentioned this to Hi-Rez and they ignored me, but you know that they know that Jorm is kinda bad when they can't stop buffing him, but who cares about fixing something that should not be intended, right? :D
*Global Ultimates are really valued in this season, so gods like Janus, Athena, Apollo, Chernobog, Nu Wa (also buffed bc of archmage's gem, tahuti and shard changes), etc, are played a lot and are being successful.
*Healers and those that rely too heavily in their sustain out of combat (like Cama/Ama) are a bit worse in general bc of the antihealing global aura, but they are not dead at all
*Tiamat, altho it's not yet here, I expect she will be probably either SS or S+(more likely S+ because she hasn't a crazy early game), her abilities are really strong in general and can be very tanky.
-Totally Broken. Picking gods on this tier would reward you with really high chances of winning.
-Best gods right here. 1st picks/bans
-Gods that are really strong and should be taken into consideration if S+ are banned. (some might be 1st or 2nd picks/bans as well)
-Mostly your meta picks. They rarely get ban and usually are good choices with/against any comp.
-Some of these gods may have more or less the same potential that S- picks have, but seemes a bit weaker. Some kinda can't be on/against any comp
- Average. These gods are 'balanced', or situational. They may seem to be powerful against some gods of higher tier or at some point of the game, but doesn't mean they are as good as that every single game. or during the whole game.
- Not Bad, but not good either. These gods can be picked, but it's risky. Some are not that hard to counter.
- Bad. I don't think these gods should win a single game if you are facing a good enemy team.
- Welcome to the Anubis tier, or worst god in the game :D
- Instaloss (None in Rankeds)
