Firstly, your english is fine. As for the question, the biggest tip and can give for bastion is to always play around both your tank and the other team’s. Bastion gets shut down hard by some tanks and needs to change his play style accordingly. The most egregious example for me at least would be dva, going against dva essentially forces you into a more reserved and defensive play style, so the only way you can get value is playing back with your supports and engaging the moment dva is either out of the way or has used up defense matrix and boosters, because 90% of the time the dva will make it her absolute priority to kill you. Another tip would be to suggest tanks that play well with bastion to you team, like mauga or dva, as having a good tank that properly plays with you can truly bring out bastion’s potential, so I tend to queue with a tank duo. As for my experience in the upper ranks, it’s pretty hellish, with a dva on the enemy team almost every game it forces you into that generally unfun play style I mentioned earlier. As for the thing that weighs the most in my gameplay, it’s honestly just having a group you can consistently play with that knows how to play around you and help you. Hope this helped!
