Free Agent - NA
This is my opinion of which gods go in which tier. This is strictly for Arena, so if you don't play Arena, click away.
I only play Arena so this is mostly based on how frequent I see the god, their overall performance (KDA, team effort, etc) and how well their abilities work with other gods. Some gods just deserve the place because of who they are (loki) while others contribute more to their team than themselves (ares). This is just a simple opinion and if you disagree, hey, that makes you human just like me.
ss
The kings of arena. These gods are always a threat and should be eliminated as soon as possible.
s+
High priority targets you should watch out for. If it's a guardian, it's because of their massive amount of CC they can lay down.
s
Gods who do exceptionally well. Most guardians get placed here due to their CC being invaluable in scoring kills.
s-
Most hunters go here, they can still dish out a lot of damage if left unchecked.
a+
a
a-
Infrequent gods who just don't have the stuff to rank higher.
b
Gods you might see from time to time but don't usually do that well due to their kit not being attuned for Arena.
c
Super uncommon gods you probably won't see in Arena for a long time.
d
Gods you will probably never see in Arena. Ever. If you do, they are either really really good, or really really bad.
