Most of that map can be fixed if they made S and A ranks spawn off Spawn nodes, IE The 3 mid nodes can only be A-S. While the others remain B's. No one really care about RNG awarding someone 2 B', but they do care if at the start of the game, the match decides to plop an S rank right in front of them for their first node (this has happened numerous times) or 2 A's right from the get go.

And please don't quote this and give me a scenario on a fight and you're amazing pvp skills on solo'ing 24 people on S Ranks, no one cares. If you're in a premade, good for you and your team. But for the other DF, you know EXACTLY what's gonna happen and what they are gonna do when S pops happen right in the beginning.
