Daopa's guide and personal take on this character:
Find a nice spot and switch into sentry mode to blast away enemies.  Get into trouble run away and go into self repair mode. Main task for defensive role character is to guard locations / objectives, create choke points and establish a front.

Bastion has 250 HP and while in Tank mode HP goes up to 400. Self-Repair can be used in all configuration modes.
