I think you should have included Shigatsu Wa Kimi No Uso (your lie in april)

I don't want to be rude, but your list is pure shit. Angel Tales, a shitty harem anime in a top 10 romance anime ? Really ? The only anime that have their place here (well, in fact, it would fit if this was a top 20) are Nana, Golden Time or "Say I love you". Maybe Toradora at the very bottom of the list if you have no idea. But even mainstream animes like Oregairu are better than the rest of these. Where are Sakurasou (shonen), Kimi ni Kodote (shojo), Clannad or even Shigatsu (Which is totally overrated because it sucks after the first half of the anime because of the focus on shitty drama) ? Ore Monogatari ? Gekkan Shoujo Nozaki-kun ? Lovely Complex ? Chuunibyou ? Nodame Cantabile ? Kokoro Connect ? Hell, even Spice&Wolf, Bakuman or Steins;Gate (Yes, I am serious) which don't focus on romance have a better place in your list. The animes I have listed here don't even belong to a top 10, but are way better than your list. They are just some that I remember. Please, consider to rewrite totally this top. Sorry for my english.

I think you should include White Album 2, Shigatsu wa Kimi no Uso and Kimi no Iru Machi in your list. And if you want action as well as romance, you must include Sword Art Online (Season 1 only I think?.
