I see it constantly.
People planting in the middle of the train carriage instead by the closest to the attacking team door so you can cover it from the side objective site. Even the other door are fine if you hold the building on the left
People planting in the middle of of the last objective at the Underground map instead close to the left stairs (so you can cover it from that room on the left.
Think.
P.S.
Also so many people don’t realise only one person can repair/disarm/plant. If someone is doing it and especially if that’s an engineer, do yourself a favour and cover his ass instead of giving someone else another free kill.
