As i was roaming through the forums a few days back i came across a post about guilds and the covenant thought that it would be a good idea to make the covenant on both alliance and horde, then it came to me why not try to do the same thing
when i reach the higher lvl's 60+ i could try to replicate the idea making the cult on the horde side, much spamming and forum posting would be called for but thats the smaller priority. Anyway leave your thoughts on this idea and add any improvments if needed
