wat? they have english dubs for these two.

Japan does not focus on creating English dub for their series since majority of their money comes directly from Japan. Most studios really do not bother much with foreign countries. However studios in America, namely funimation, works to dub most popular series and have recently reached out towards ongoing shows as well. Just go to the Funi site http://www.funimation.com/videos/episodes and change the language to Dubbed (idk y is it not just english instead) in the search function.

Reasons to why people listen to Subbed is that 1. there is more series. 2. The way each voice is originally portrayed comparative to a English remake. 3. Japan has more pride in their VA so the quality of work is much better compared to America.
