help me with unholy pvp

[Mr. Casual]

hey guys, i been wanting ti try unholy pvp and i wanted to get a basic rundown on damaging attacks, like festering vs scourge...etc. been trying to find some type of guide but since frost is the popular choice i cant find much. Unholy has so many more attacks im having trouble figuring out what to press. festering, scourge, necrotic, deathcoil, diseases. what attacks take preference/do most damage

Read the tooltip of every ability, several times and everything will become clear. If not I guess http://www.mmo-champion.com/threads/...ndaria-Edition could work, if ur up to reading a wall.
