You know why I love the Dead Ringer?
So many times I've killed Engineers, thinking they're so safe beside a sentry, when I (after killing someone else for their disguise) kill them while they pound away on their sentries.
Did that one glorious time today, their entire team was pushing up towards the spawn, I managed to sneak past them (hooray cloak and dagger), and killed another engineer at the spawn as he was tending the dispenser, away from the sentry's sight.
Killed the engineer just still beside his sentry, sapped them all, capped the last point quickly before the team could get back.
Aww yeah game changers ftw BV
