Such 70-200 f2.8 is not designed for landscapes, it's designed to cover both people photography (full body, 2/3, 1/3 and head shots) and sports from perimeter of playgrounds where you don't need a 300 f2.8, the 300 f2.8 will frame too narrow. You have all Canon, Nikon, Tamron, Sigma and Pentax staff who designed 70-200 f2.8 zooms , there must be a reason (a significant market) or you are smarter than several thousands staff of camera system designers and marketing who have been doing their job for many decades. Primes have different roles, they are more like additional options for very specific conditions. Professionals use what they need for the situation, not necessarily a 300 f2.8, can be a 70-200 f2.8 as well (why not?), they use 70-200 when close enough and 300 when further away, they observe the situation and adapt to it, and 99% of the pro don't argue in internet forums, they are too busy to do their jobs correctly. I know a guy here who is photographing the Olympic games: skying. He use a D5 and 400 f2.8, 200-400 f4, he goes 3 days before the D day in order to assess the place, review schedules , weather forecasts etc, he doesn't discuss on internet forums, the difference between internet forumer and pros is that the pros are pragmatic based on solving problems in the field, while internet forumers argue because they want to be right without a situation that define choices. Internet forumer who read DP reviews don't learn anything other than comparing camera gear specifications without knowing for what it's designed the way it is.
