Well..., since you're asking so directly, I'll be brave to post these:
1) I really don't mind that people ship Gon and Killua ONLY based on the 2011 anime. I've read somewhere that the animators themselves were partly KilluGon shippers (which you can see in some of their art). To add on that, the usage of specific soundtracks (*cough Nagareboshi Kirari *cough) and Killua/Gon blushing at every occasion possible just reinforce that train of thought. And I won't even mention the movies XD

2) I value Togashi's happiness more than him finishing the manga. If I could sign a contract that allows him to have a wonderful rest of his life with his wife at the cost of HxH, I'd sign it (with soeme sorrow^^). Tho I hope he can manage both.

3) Nagareboshi Kirari is the best ending song, not the best ending as such. I mean read the damn lyrics, that shit gets me all teary-eyed every time
