So...DK is really the only class that I haven't tried. I've decided that I'm going to play one. Basically, I'll just be PvPing through the upper-tier brackets. While I have a good idea about the playstyle of pretty much every class, I have to say I'm basically clueless with the DK. I'm not so ignorant about how to handle specific classes. I know how and when to use big cooldowns like AMS, Deathgrip, IF, etc.
My question has more to do with basic rotations. I'd like to know how to get the most damage out of plate fights, how to most effectively burst, how/when to use AoE, and when to use some situational abilities.
1) In a non-burst fight (against a paladin/warrior/DK, for instance) what rotation should I be using? Do I pack him up w/ diseases before I scourge strike? or just start hitting him with it?
2) In burst fights, does my rotation change?
3) what's the most effective method of dealing with 3-4 enemies in melee range of me? What AoE abilities should I be using?
4) In the middle of a fight, at what priority do I use abilities like bone shield and corpse explosion?
