Overwatch's principal designer Geoff Goodman shared on the Battle.net forums that the team is looking to rework Bastion's abilities. They're not completely revamping her, but they're increasing the hero's viability in more scenarios.
At the moment Bastion very much plays out as a "corner camper," holding down a choke point. With a proper shield, Bastion can lock down an avenue of attack until forced to move or until death. The development team, however, don't want the hero to be played in only one way.
Here are the changes the team is looking at:
Recon Mode - Lowered spread and increased magazine size, to help with general viability in this mode.
Sentry Mode - We're looking at focusing this mode into more of a tank-buster and barrier-buster mode, while also making it feel less suicidal to be transformed. To that end we're testing stuff like increased spread and removing headshots, but taking less damage while transformed.
Self-Repair - We've been testing a few big changes to this that are feeling really good so far. Currently our internal build has Bastion able to use Self-Repair while moving and also having it no longer interrupted when taking damage. To balance that out it is now on a resource system (similar to the route D.Va's defense matrix went). These changes have turned this ability from a more niche rarely used ability, to a much more powerful and core survivability tool.
Overall, Bastion will be more deadly on the move, as they don't want players to only feel useful when they're in Sentry form. On the same angle, the DPS in Sentry Mode should be reduced as the spread is increased and headshots are removed.
"We're still testing and tweaking things with Bastion," Goodman finished. "But we'll hopefully have a PTR build coming fairly soon so you guys can try it out!"
The Bastion changes coming to the PTR are not yet set in stone, but the Overwatch development team is definitely looking to overhaul a few of the hero's mechanics.
