That is kind of weak. I have gotten with a torcreep explosion to destroy all of the building except for topping on the staircase on it. Besides that I could even destroy the base plates. HE also does a nice job of destroying buildings.
Yeah, I know. I've gotten the whole build before too, even before HE grenades and torcreepes by putting FakeKill on the baseplates.
Anyway, the whole point of this wasn't to destroy the whole building, it was to get a bit of a benchmark for pre and post V11. The detonation cord flashes were just a nice effect for the 'controlled demolition' feeling.
