It is also on a long cool-down, unlikely to be used twice in a fight, very small radius and you can still Immob or CC (in any form you deem pleasing to yourself) the Engineer to keep them from trippin’ you. Additionally you could just stop moving for a second.

Get good or get stability.
There are better alternatives, anyways.
