I guess they must have had some purpose for building 4 WTC first alongside 1 WTC. But in my opinion 2WTC should have been built along with 1WTC. I am willing to wait for 3 WTC and 4 WTC which are more nondescript and less visually stunning. But 2 WTC has a beautiful design that would make a great sister tower to building 1. I do hope it gets built sooner rather than later, but tenants in the 3 other towers have to get filled up first. Bummer
