This is my tier list about aspects in smite 2 at this moment.
In S tier I put the aspects that you should always pick and definitly you win more than you lose, these aspects are very good and might get nerfed with Ra and Mordred being the most OP aspects right now, Mordred being able to reset his dash is ok but he procs item effects on each and that makes it broken. Ra aspect gives him more survivability and also makes his ult that you can never miss.
In A tier are aspects that I think are good and balanced you either pick them or don' t except the morrigan one that is very good but you have to know very well to play in order to make it work.
In B tier are aspects that work in certain matchups and are ok they also change the god play stile a lot.
In C tier are aspects that don't really work and if you pick them you need to have a specific build in order for the aspect to work in your favor.
In F tier are aspects that are so bad that can make you lose games. With that Chac aspect that makes chac so weak, Herc aspect is support oriented but if the enemy knows that you have this aspect they will avoid hitting you with autos so you get nothing out of it. They should redo these aspects.
