Thanks for all the manga recommendations. Just to clarify, I've read much of what been listed here like Boku No Hero Academy, Berserker, Gunmm and Full Metal Alchemist.
I'm reading Gamaran right now. I think Gensan Ashua is better (superior art, better pacing) but I like how Gamaran try to explain some of the manuevers and strikes the fighters do.
The Symmetra buffs are up in the PTR and I think she'll be the new Mei. Both have slows, walls, easy to aim weapons, solo kill potential and faster filling ultis. I'm already ready to swap my "sorry sorry sorry" for "such a lack of imagination".
