There is actually quite a few things i'm quite interested in for Legion. Demon Hunters are definitely big on my list as I've wanted them as a class for so long and will finally get the chance to play one. Also looking forward for PvPing this expansion due to the new talent trees. I love the idea of Artifact weapons as well, since it brings more class identity back into the game, and the fact that theirs a decent amount of customization with all the various skins.
As for my fondest moment in WoW, its hard to say. The 11 year old me would like to say witnessing Highlord Kruul attacking Storm
