I'm just going to chime in with a comment on the picture of violent anime heroines. Lucy/Nyu should be the teacher and everyone else are students. Lucy would easily kill everyone. That is all.

If I'm streaming, I use Hulu, Crunchyroll, TheAnimeNetwork (been more wary about using their site as of late due to recent lack of dubs), Funimation, and sometimes Netflix. I try to stay away from illegal streaming sites like gogoanime, WatchCartoonsOnline, AnimeFreak, etc. I don't want to be a hypocrite and say "I don't like stealing anime and I want to support the people that make these awesome anime" because I also download a lot of stuff from Nyaa. Although, I try my best to support the anime economy the best I can. And If I watched the show illegally first, then I make an effort to purchase it later...even if I didn't like it. (That's what I did with World Of Narue, for example.) Of course, the other reason I don't like using the illegal streaming sites is because the video quality is usually shit. So if I really want to watch an anime that I can't watch legally, I'll download the highest quality torrent (which is usually a Blu Ray rip) To buy stuff, I use ImportCDs, Amazon, Rightstuf (you can buy other kinds of merchandise there too) , GoHastings, and DeepDiscountDVD. There are usually some great deals that can be found there. If you want to download anime the legal way, there's a shit-ton of anime on iTunes and Google Play. As for 18+ content............I use Fakku. Hentaikey has some pretty cool stuff that's licensed and uncensored. Though it's not worth it if you don't have a Roku (You need a subscription to watch their content). Pururin is dead. Doujin Moe/H-Moe is pretty good and so is H2R/H2W. A lot of uncensored DVDs are available through Rightstuf as well. Hope all this helps. :D
