1. Caps Lock is not cruise control for cool.
2. What was your DPS when you got kicked? Need some numbers.
3. Check your gear.
4. Your talent build is just plain horrible.
Let's start from the end, shall we? Your talent build sucks. Simple math says that if your talent build sucks, you're bound to perform less than optimal.
Sudden Doom - get it.
Bloody Vengeance - get it.
Bloodworms - dump it.
Vendetta - dump it.
Anticipation - dump it.
If you want Epidemic and Ravenous Dead (+3% str), put points in Vicious Strikes and Virulence instead of Anticipation. Death Coil procs from Sudden Doom make out a pretty large chunk of your DPS, so you want to make sure they hit. And since you'll be using Plague Strike regularly to apply Blood Plague, Vicious Strikes will add some DPS there. Besides, anything else is better than +dodge for PvE DPS, right?
You need to decide if you want Butchery or Blade Barrier. You probably want Butchery for the extra runic power generation. Dump the point in Blade Barrier and get/dump the talents mentioned above. Vendetta and Bloodworms are for leveling and PvP. Bloody Vengeance will increase your DPS by 9% when fully stacked, which shouldn't be a problem with decent gear.
So, that brings us to your gear. Which is also horrible. You're wearing a mix of PvP and PvE gear and the PvE gear is split up into tanking and DPS. Your shoulders and necklace items have +defense on them. Your weapon is a level 75-ish quest reward. One of your rings has +armor on it and you have a trinket with haste. What happened to your Death Knight's Anguish from Borean Tundra? Surely crit rating is better than haste rating and a passive proc is better than a on-use attack power boost, in my opinion.
This goes well with my second point. What was your DPS at the time you got kicked? Maybe they were overreacting or maybe your DPS truly did suck. We can't tell without numbers. Was it 1k, 2k or what?
And finally, don't use all caps in your thread title. It's a sure way to get flamed.
