Bastion is pretty easily countered with someone like a tracer that can get up close and sticky bomb you, or even a hanzo or widowmaker that can peak corners for a split second and 2 shot you or 3 shot with pharah rockets, so hes only OP if no one does anything about him! Some of the other heroes though definitely need some adjusting, Mcree for example needs a nerf, and Blizz did say he's going to get one. Personally i think hes fine except for the whole rolling ability that reloads his gun which makes taking out tanks very easy. Flashbang, fan the hammer, roll, fan the hammer and they're dead.
On a totally unrelated note i recently picked up a 12gb ps3 for $78 brand new (praise ebay
) and a 1tb sshd with a bunch of exclusive games for pennies so i'll be pretty busy this summer. It's tempting to get a ps4 for Uncharted 4 and some Bloodborne, but with all these rumors of a newer beefier ps4.5 on its way i think i'll wait for that instead. Not in a huge rush anyway
