My frustration with Bastion has nothing to do with its damage output. Bastion’s ability to heal itself (with no real cooldown or penalty other than losing the ability to shoot as you’re welding yourself back together) is one of the biggest reasons it’s Overwatch’s least-interesting hero. What would Bastion play like if you couldn’t self-heal? You’d probably have to communicate well with your healer, knowing when to call in their help without depriving your teammates. You’d have to pay more attention to your team’s positioning, making sure you’re reasonably within reach of that healer—you’d have to play differently depending on which supports were in play, even. Or you’d have to dart away and find a health kit, using your map knowledge and intuition to pick the right moment to abandon your post (and perhaps robbing a teammate of that pickup in the process). The proximity to health kits would make certain deploy points more viable than others, perhaps adding to the meta of each map.
