Is it really that hard to tell the difference between Jeff's response and Ornyx? Jeff responded to a player who should have never been responded to, the guy offered nothing, but Jeff responded in a catty unprofessional manner. It's also important to keep in mind what game is being played here, Overwatch. As long as you have a solid 10 or so games under your belt you've effectively sampled 100% of content.
Ornyx responded to a guy, making an underhanded reference to not having anything to do in the game except grind AP. Ornyx called him on it. This guy is criticising an aspect of the game when he hasn't even sampled everything he could be doing.
