I would make all of his transformation speeds faster.
I would also allow him to go into āTread,ā mode. While in āTread,ā mode he cannot attack, however his ironclad is increased and he can self heal. He creates a mini version of himself, and climbs up walls.
This way he can make himself smaller/harder to spot/hit and get to places that he currently canāt reach without a Mei.
ETA: They can use the old model for his original ultimate perhaps.
ETA: Also perhaps give him a small hop while in this mode.
The reason that I think this would help is I see a lot of good Bastion players constantly changing position or trying to hit from unexpected places, but they can only do that so much because heās big and slow. If you just made him run faster heād be a better Soldier 76.
Because heās not moving any faster and heās not putting out any damage, this wouldnāt be as useful as a disengage as Soldierās sprint. But because it wall climbs, he could get to spots that Soldier couldnāt get too as easily.
And since it makes him smaller, it would make him harder to spot while he changes position.
eta:
This is what his old ult used to look like and the size I think he could become.
