Yeah I just beat GoW1 for the first time and Ares was super easy to defeat which was unexpected because some of the other boss fights were much more difficult.
Staying on topic though I actually may change my gameplan as well and rock Ares I enjoyed using him in the beta and like someone else said everyone is gonna want their hands on Hades or Posiden right away since they weren't in the beta. Dunno though I may do what I did in the beta and go class by class little by little would go in 10 level incriments. Got to level 10 with Ares then used Zeus for 10 lvls rinse and repeat.
I don't really think that he is all that noob friendly realistically they all just are going to have their strengths and weaknesses. Zeus is good for magic however I had a beast of a Ares fighter. I had him with over 300 armor and close to 300 damage so I was killing people easy while being well protected.
