Hello I have Guinevere, Delilah, and Poseidon. Who do you think should be ascended to tier 4 first?
I would go Guin 1st, Delilah 2nd.
But it still depends on your needs and rest of your team.
Delilah is also awesome she is really usefull. Guin is one of the best tanks. Posseidon one of the best snipers.
