2. Completely disagree, ace game decider should be as balanced as possible so the player with the best skills, endurance, and strategy reigns supereme. Not whoever can think fast enough on an unknown battlefield
4. Dying troops with low visibility is not fun for anyone. We suffered it in tournaments for two years, and for those of us that remember it was just... shit.
2: Strategy should be adaptable. Skill is too. Endurance doesn't depend on a map.
Having a randomised map means that an additional skill players must hone is adaptability, and knowing the basics of a wide pool of maps. Encouraging players to know exactly what to do on Crossroads 100% of the time leads to situations where we could have Kimbo, VonIvan, Isildur and Noggano all play USF and overlay them with minor variation.
You yourself mocked the Spec-Ops meta. This would help alleviate that kind of situation and, in my view, provide a better viewing experience as people see players adapt and strategise on the fly.
4: That's why I'm thinking a side event. Especially if there were a map or two curated for it, to mitigate the worst parts. Fixed interval blizzards, good provision of cover and heat for the early game so that late-game vehicles destroying it becomes a tactical decision..
