You mentioned lag. I would add rubberbanding to go along with that. And to be humorous you could mention the fact that in almost every set of patch notes several issues of rubberbanding are mentioned as being fixed, yet it seems to never permanently go away. Or maybe that's just my own sick version of humor... :ph34r:
Barblo, an amalgamation of the words Barb and Diablo, referencing the idea that the game is built entirely around the one and only Barbarian class, while completely neglecting all other classes.
Also you might want to add that hammer of the ancients is also sometimes abbreviated HOTA, often said as a single word, rather than saying each letter individually, and tends to be the build that barbs use most often when attempting to set records due to it's high single target damage. At least, that's how I've often heard it mentioned.
Btw, very nice work you have done here. I enjoyed reading and can't wait to see the list grow.
