Tbf, as a Driller main I, too, drill straight toward objectives. Though I’ll ensure I don’t drill at too steep an angle, since I don’t want to have to bother jumping off I can avoid it. I’ll also drill straight toward the escape pod from whatever room the group is in, which usually winds up helping everyone.

In my group, the person that usually plays engineer has the nuke OC, so I’m generally not the main source of friendly fire. I do fight giant bugs’ with C4, though.
