I'll be straight here: I game on my 2016 pro 460 MacBook. It's a very pleasant experience for the titles I run [Mostly Blizzard stuff, Overwatch in Boot camp] When I'm in a match in HoTS, even though I'm not maxed out [shaders medium, 2880 x 1880] It's an absolute JOY to game on. The lack of settings is made up for by the glossy display.
My other machine is a 6700k @ 4.7Ghz with an Asus Maximus IX Formula Z270 Motherboard, 32 gig DDR4 3000, and freshly upgraded to dual GTX 1080 in SLI, running on an LG 27UD68 4k monitor.
Not exactly a fair comparison, I'll grant you, but the EXPERIENCE is roughly the same. My desktop is more built for my Oculus Rift, but it's buttery smooth with anything I could possibly throw at it.
And when I need to be in the other room hanging' out with the kiddo, or wanna sit with the wife for some HoTS, I can do that and still be just as comfortable.
It's NOT a bad laptop for gaming, as long as you know it's limitations.
