Mean and would you say that fourgate was enough to get into Diamond?
From what I've heard from a lot of high level Protoss players; the general consensus seems to be that 4gating can get you into diamond; and according to Benji (from his streams) it is able to teach you somewhat decent macro (in terms of keeping your warp-gates on cool-down and so on).
But in my opinion; the macro you learn is only up until the 8-9 minute mark where you've either won or lost the game; not longer-game macro nor the ability to be able to think of the fly and deal with an array of scenarios that could be thrown at you (i.e. a Terran opening with cloaked banshees, or a Zerg who holds off the 4gate). That's just my opinion though, so take it as a grain of salt
