WoW still a good niche to go with, but make sure you target some low competitive keywords that's your only way for search engines traffic..
I see you're using only WP-Robot for content generation, well will be better to add rss feed content from a number of WoW related sites/blogs, news content is much better for this niche than old articles if you ask me .. use other plugins for that .
Edit your right footer sidebar, remove meta and any outgoing links, put there latest comments or some thing else, you need to write some thing in About Us with your main keywords, make it unique at least 350 words, also Top 5 Guides where is titles ?
Setting a..ds..ense within the first day is a bad idea if you ask me, wait a week or two then place it .
In my experience black themes like that does not convert well, you can find tons of other WoW themes in clear colors and even better themes than this one .
Promotion : back links! social bookmarking, stumble, post comments in WoW related blogs, joint WoW communities and forums ... well you know .
One blog will not make you rich

, move on to your next autoblogs ..
Good Luck .
