icic.. i was trying out warlock skills yesterday... what i did was

Send Pet > Corruption > Siphon Life > Life Tap > Drain Life > Life Tap > Drain Life

If more than one mobs then i'll just Siphon Life the second mob so i won't aggro so much... Void Walker to on the aoe tank spell (forgot which one liao)

Curse of Agony take too long to fully exercise its effect imo. Corruption and Drain Life will have 4% chance (i think) to activate Shadow Trance i think with talent, so i just use those 2.

Using the rotation, i dun have to sit down and drink/eat = no downtime while farming mob. 1v1 can take up till lv49-50 mob i think haha

Just some feedback on using lock.. i'm interested to see UA in action too =D
