That's a good answer. But I'm gonna take exception to a couple of points.
First: "with BM and Olympus, especially below diamond is that all teams jump in a couple of poi." This is not a map problem. It's a player problem. My personal experience is that this happens on all maps, and that, as you noted, the behavior changes as you climb the ladder. And the developer could change all of this by designing donut-shaped maps. But they don't. I have to assume that's because they want that skill-differentiator to exist. The maps are there to test the players. If they all fail below diamond then that's intentional and happens to encourage more serious players to find a squad. Which is something they should be doing anyway if they intend to make it through diamond or whatever that new try-hard tier is called.
Second: And I don't want to delve too deeply into this because it's been litigated enough and I'm not here to set anyone on fire, but I couldn't let this go without a response: "Dropships cause hot drops." Dropships don't cause anything. Hot drops are caused by inexperienced and impatient players and absolutely nothing else. Drop ships are a tool and it's up to the players, or at least up to the jump masters, to decide how to use that tool. Just because most players use it wrong doesn't mean the tool is inherently bad or at fault. If a drunk driver kills an innocent pedestrian at a street corner... who or what is to blame? The beer? The car? The pedestrian? Nope, it's the drunk. And you can try solving the problem by taking the beer away from him, but he's still weak, diseased, or stupid, depending on your point of view. And I'd wager whichever quality is at fault will find other ways to out even in the absence of alcohol. Sorry for the labored analogy. Up shot: Either start abandoning your idiot jump master or, as before, find a squad. Which is what you should be doing if you plan on blah blah blah. You know the deal.
Lastly: "I want to play the game, rotate and fight late, but when maps are designed for high-action early game fighting where all teams go in a couple of highly populated poi, it misses the entire point of what a BR is about." Your instincts are both noble and correct. This is exactly how you should be playing your matches, especially if you're grinding for a high rank. But on what planet are maps designed for high-action early game fighting? They're designed for whatever kind of fighting - early game or late, high-action or low - the players decide they're for. If you're discovering that most players have a "casual competitive" mindset and that's making your life hell then I sympathize. I belong to the same minority that you do and it makes it very hard to grind ranks as a solo.
So I'm not saying you should love all maps equally. I certainly don't. But think carefully about the reasons you dislike something, and ask yourself if the fault really lays where you think it does.
