i got a solid group of 5 friends i play with, which makes this already super fun game worlds better. so ill usually pick what character is needed at the moment. but my favorites would be mei (for both point and payload maps), junkrat (once you get good with his remote mind, hes pretty devastating), lucio/mercy (though im starting to use zenyatta a lot more. SUPER FUN) and love being 76 as an offensive player and a makeshift healer on payload maps.
currently level 15. which for me is pretty damn high considering its only been out a week.
what enemy match ups do you guys hate facing? im starting to see a lot of double bastions, or bastion/trobjorn with double reinhardts, a healer and mei. pretty annoying composition if youre soloing and have teammates who try to break it on their own
