Well I am not Zen..
I gave a shot at zones while farming loyalty and best I can reach is zone 40.
Once the speed reaches Zen level I start to go down fast :(
Will give it a last shot tomorrow as I still need 10k loyalty but I don't expect to get trophy by then and I'm not planning to play the game more after that.
I've noticed the level of concentration needed in zones or phantom races gets my eyes tired whereas usually I can play any game for very long stretches and never have a problem..
PS : I will only be going back to Warhawk a couple days till I get my next game supporting trophies..
