i dont know how much u know about locks, but u need not buy any food or water. all u do is spec affliciton, get improved drains so they have a rare chance to be interrupted, dot once(therefore casting 4 total dots) life tap, drain life. rinse repeat. u can literally go for hours on end just a tip. like i said i dont know how much u know about locks so im not sure if u knew u could do this. also u r absolutely right about the wands, id contend with 4 pets u wouldnt even have to dot, just /petattack /use wand and theyd die before they got to u.

as for pvping, affliction would be a good choice, be sure to get the increased range on dots of course if u do go with felguards since they will rape casters by themselves. i could only imagine 4 locks standing on the road tossing up simultaneous dots >< insta corruption followed by SL, then curse of agony x 4? gtfo lol thats gonna suck to be on the receiving end
