I was thinking about it recently, I’ve made some suggestions in the past but if we were to keep him the same but add an E then maybe he could use a Railgun.
I like the idea of Bastion being a bit of a swiss army knife of war and from a gameplay perspective he really lacks a reliable ranged finisher and lacks mobility.
I propose we give him a Railgun on a long cooldown (12 seconds?) with a small ‘charging’ animation. (delayed fire like Mei gun but with an audio cue for the enemies)
The railgun I propose fires through enemy barriers and hitboxes (allowing Railgun multikills) but does only a reasonable amount of damage (maybe 100?).
Lastly I propose a that the Railgun is so powerful that it launches Bastion backwards a massive distance (10 meters?) and stuns Bastion if he collides with a Wall but if he uses it in Sentry mode he is not knocked back and cannot be stunned by using it.
