Inara's Impasse has very high health and can be annoying to take down, especially without Bulldozer. If the enemy Inara happens to use it near the payload, remember that if the payload touches it it will instantly be destroyed.
USE YOUR WALL! It blocks fatal attacks, (Terminus ult, skye ult, ruckus ult, willow seed, BK grumpy, etc...) Most healers need line of sight to heal. block vision from a single target with your wall and burst them down before their healer can react
