Resigning form transports was a great move of civ5. That step was exatly the one where global strategy like civ should take. Simirarly city defenses. But this 1upt spoiled those small good steps. And I can name so many more small things where CIV5/6 goes in good direction, comparing to 4. Some bad as well, but the list of good things is longer. But 1upt really cancels all good things as it ifluences much more areas than warefare, diminishing Civ srtrategic depth.
