Poor Bushwacker.
The only balance change of the latest patch is to increase the cooldown on relocating his turret, by reducing reclamation cooldown to 65% from 80%.
The turret is the only thing old BW has going for him - and at its best it is a gimick for luring noobs to their death.
When deployed against an experienced player, the turret is of very limited use. As soon as they hear or see the turret, it goes down in short order.
BW turret has very low health, and the redeploy time was already a bit much.
To be "successful " with the turret, you need to relocated it often - and that’s not going to be happening with the additional redeploy time.
Too bad. I liked to wack some bushes on occasion, even though most times any other engineer would have been a better choice.
