Hands down Warrior Lord of Light.
I have him maxed. He has taken my arena team to new levels.
I have won battles with him just counterstriking on his own.
He hits all enemies hard, he reduces Hp every hit, he cannot be stunned, his passive when maxed counterstrikes when allies are attacked.
With Viper talis and a good Cosmic, he is the last to die on my team.
Look at the top 50 arena players.... he's the most popular LoL.
Killer Prime & Gambler Eddie are must haves for FC too.
I do have Beast awakened level 8, but he is not as durable as W. LoL.
I would not, nor do others really use Beast in arena/pvp.
Btw, Osiris did a couple of memes showing how hard it is to go up against W. LoL, check them out here:

Good Luck!
