It's human to get upset about things. And sometimes, it's human to get upset about the most trivial things, because they're the safest things to get upset about. I often view World of Warcraft through this lens. Indeed, I view it through a great many lenses, because it's impossible to not apply my life and my experiences to everything I encounter in this world from events of great personal significance or global importance down to the video games I play. And it would be fair to say that World of Warcraft has more than a passing importance in my life, considering where you're reading this.
The recent change on the patch 5.4 PTR changing the Glyph of the Weaponmaster was, in real terms, completely insignificant. A cosmetic glyph in the first place, the idea that it worked with legendaries was nice, but hardly significant. I mean, I play the game now and I can't use my legendaries, so what changes? Realistically, nothing changes. And yet, I wasn't merely disappointed by the change. I was outright enraged by it, far more so than I have been by direct nerfs to my class of choice.
Part of it is due to attachment -- we invest time and effort into these avatars of ourselves, after all. But in the end, much of my anger was rooted in the fact that this was something small (in relative terms, since all of WoW can be considered small compared to many of the shocks and calamities of our actual lives) and harmless, that gave our characters nothing in terms of power or ability, that imbalanced absolutely nothing in terms of gameplay, and yet it was still taken from us. Sometimes, the smallest cuts hurt more entirely because they are small.
