This is a deal breaker and incredibly key part to the change sundy placements rules last year.
There is now no building anymore which can be bunkerd till the end of the day.
You can use it as a defense to clean the point or even for attack.
Just imagine Indar Comm. Enemy pop is rising and they push out of the spawn....but then you set the strike on the building in between.
Actually it's even a question how much security do you get in a spawnroom.
If you build one strike in the middle of Ceres and Allatum Bio Lab you should be able to get plenty of bases in range which are often contested.
It just need a bit of preperation. But i can say as i didi it with Synho already: You can set this strike with fly by from a Valkery or just with a cloaked flash....and nothing is more bad ass as ruining the day of a huge group with one little glowing bullet from the seat of a Valk.
