It seems like both sides of this argument have valid points. I've often observed on streams that players can spend up to 10 minutes just analyzing the map. Naturally, this ends up consuming a significant portion of the early game timer. Later in the game, when more strategic thinking and efficient actions are required, they start clicking frantically like crafters. If the game ends quickly, this strategy can be effective. However, in a mirror match, direct contact before the middle of the second week is unlikely. After that, the faster player can take advantage of their opponent's time pressure. Overall, I think it's best to leave things as they are; you can't please everyone.
By the way, even the 4000+500 turn timer in Versus mode sometimes wasn't enough.
