While it's true the numpad is almost always not used in games (even for macros it's not best to use since you have to take your hand off either the mouse or use your WASD hand to use it), I use the numpad outside of games all the time, whenever I have to input a number - it's just so much faster than plugging away at the top row numbers.
Sure it's a "gamer keyboard" but even competitive gamers use their computer for other things outside of games. Once you lose the numpad you'll start realizing just how much you actually used it.
I get it, Roccat is trying to cut costs by cutting down the number of keys and the expensive cherry mx switches that go with them. But as others have said this is unacceptable for a $140 keyboard. If they brought it down to sub $100 I could see it, but that's just too much to sacrifice the numpad.
