Well, I've put an hour into Baptiste and haven't got either of his trophies yet. I find him too challenging to be honest. I think I'm ok with him as a basic character, I can multitask and get plentry of kills/heal teammates like I do with Zen, but I'm pretty useless with his abilities, his matrix and immortal field ult. I can never deploy the matrix in a good moment and his ult gets destroyed within seconds.
I tried Ashe today for one match and had a great time, definitely going to have fun with her combat style. Going to feel weird being unable to heal myself though, I'm too used to support characters, and have zero faith in my random team mates to heal me. Time to memorise where the med packs are...
