I could be wrong here, but I feel like OP might be Criticizing people for literally bum rushing with reckless Abandonment.
And then going Full Quin and yelling "Where are the Heals!?" when they run to far ahead and pull way to much. Especially with a Sprout Healer.

Just speculation, ive run into a few Sprout Tanks bum rushing. Just recently did Thousand-Maws with one.
