Mastering new gods

As far as the assassins go I'd say Susano, Da Ji, Camazotz are all pretty easy to get down. Nemesis, Rata are medium skill (combo dependent but viable if you miss), Awilix/Serqet are by far the most tedious on this list. They are both Glass Cannons that require you landing your combo correctly pretty much everytime or high risk of death or a failed team fight for missing. Both are also heavily dependent on team composition as well.

As far as the supports go Terra, Sylv, Ganesha are all very easy to get down. Faf and Artio require a bit more skill/combo knowledge to get the most out of your kit

Ganesha, Fafnir, Terra, and Sylvanus are some of my lowest mastered supports, but also some of the most underated ones.

Ganesha right now is meta in almost every game, but some people don't realize why this is. His silence is about 2-3 seconds long, and can be focused to 1-3 people at a time, and moves around. Think of the shutdown potential with something like that: a mobile CC. His ult has two major uses: teamfighting and blocking off pathways. In a fight, put in the center of everything and just watch the numbers roll in, due to its protection debuff and slow. The damage around it, while small, is very off putting and forces enemies to find a new route, which can stop chasers.
Fafnir is all about the prolonging everything and being greedy (get it?). You pop that dragon form, and you are obligated to do something with it. Hit a stun right here, another stun there, a quick team attack speed buff and boom, their T2 tower is down. That's the main thing about playing him is that he's not a usual support. You have to get in the carry mindset and just ignore your teammates in your ult and start racking up damage numbers.
Terra has been really underappreacited lately, ever since she lost her root. Don't forget that her ultimate 1. Takes away ALL mana costs, meaning low mana resources doesnt matter. 2. Reduces all cooldowns, meaning more spammability. 3. Increases movement speed, meaning chasing and rotation/gank potential. 4. Heals upon taking damage, which can save lives and prolong fights just so everyone can either make it out alive or with some kills. Paired up with her out of combat heal and/or AoE slow, and you are supporting literally everyone on your team at the same time, at all times.
Sylvanus in season 5 is being picked back up because his splash damage autos are no joke early game. This new Hunter's Blessing, and he's soloing like crazy. The flowers under tower for the ADC to stay in lane more, while also rooting to setup for a solo kill or gank, very potent. His whole kit just screams lane dominance. That's not even talking about his single person stun, which can take out either the damage sponge or damage spout of a team.

All of the above supports are great in the current meta, just find the one that suits your playstyle, most likely Fafnir.

Ganesha and Sylvanus are both fairly simple and nice to play

Thanks for the feedback, thinking I'll record/stream some games after work today :p

So far it's looking like:
Nemesis always enjoyed her tbh.
Serqet, I guess she is to good to not learn how to play properly. 😪
Sylvanus, Hunter's Blessing all the way (at least until I get into some half decent games.
Ganesha seems fun, but how do I carry if I cant KS? 😣

Probs going to throw in some Ratatoskr as well, because I've wanted to learn him properly for a long time now.

Be sure to ask Bran about Ratatoskr, he's a master.

Imma say learn Serqet first then Nemesis for the assassins. From there you can go whenever (But I do recommend Awilix -> Ratatoskr -> rest)

For Supports, Sylvanus is a really good god to have in your sleeve, he's pretty good all around and his playlist is really different, which is enjoyable. Then, Ganesha is pretty good. I personally dislike Fafnir a lot, but he's strong. Terra and Artio are REALLY fun but their numbers are just... sad

***uiming this is for Jungle/Support in Conquest.

Serqet and Nemesis allow you to cover both roles.

After that i'd do the assassins in the following order: Ratatoskr, Da Ji, Susano, Awilix, Camazotz

Supports: Ganesha, Fafnir, Sylvanus, Terra, Artio

I have Artio last cause she tends to do better in solo while the others are primarily supports. She can be really easy to punish from support if you end up behind early on.

For Assassins, I'd personally recommend Nemesis and Awilix. For Guardians, Ganesha, Fafnir, and Sylvanus.

Nemesis can be very strong when used correctly (as I'm sure you know), and a skilled Awilix player can wreak havoc all over the map.

As for the supports, Ganesha and Sylvanus are really good when you land their skill shots, and for Ganesha, utilize his ult correctly. Fafnir, in my experience, can be strong if you have a knowledgeable ADC who can play with you correctly. In casuals, teammates don't always take advantage of his Coerce boost and the disarm from Underhanded Tactics effectively.

I'd say Ratatoskr and Susano on the assassin side for their overall mobility (yeah I know Serq is also very mobile but bleh).

You already know Sylvanus pretty well from the match I saw...I'd say Ganesha and Terra probably for Supports. Ganesha seems like he's had a great overall balance almost since his introduction, and so you shouldn't see a whole lot of changes to him over the course of the season. As for Terra, you have access to that great Terra guide from NKE07 with tons of info to help you get very familiar with her.
