ok plain in simple...dest is best for PVP because the big crits wipe out anything...yes it takes up alot of mana but trust me its worth it....now its not bad for PVE but after lvl 50 i think demo is best for PVE....but deffinatly dest is best for PVP....all the low lvl locks out there wont ryl see how good dest is for PVP because u dont have ur ryl good spells yet in dest.....and if a aff lock and a dest lock were to battle the dest lock would wipe the floor with them because of neither protection....and it also help against SP's...if u wanna be ryl good in pvp or just one on one go with dest... dest has many moves that allow u to get the kill and get big crits...i twinked out at lvl 49 for a long time so when i got to 60 i would already have enough for my epic lvl 60 set... and i was almost always the top killer...and if i wasnt top i was in the top five....and that only happened like once outta every 2 months....my lock is now working his way to 60

im on Mok'Nathal sever....UD warlock....NAME:Ichor

hey im a lvl 52 dest lock, im was very impressed by warlock destruction talents espessially ruin, reaching up to a dmg of 1700 crit with soulfire :D. This changed when i saw a few demonology locks in action. Not only felguard crits often, but less mana is used (dest locks must always carry mana pots with em). What is the best for lvl 60+? Anyone experienced enough pls reply :)

Im destr/demo lvl 54, and I dont mind spending few gold on buying and carrying mana pots , my main focus is  kicking ass, plus i do have a few points in affl, just so i can use mana/life drains , they help a bit, most the times I leave a fight now not having to eat and drink :)

Wish you were in Shu'halo, my 68 Affliction lock "Undertakeher" would hand you your butt and still keep smokin. To bad your in another realm. Maybe I'll make an Affliction lock there and come spank you. Destruction is very good, but to say that it can own Affliction locks is just plain stupid. And even if you do kill me, I'll watch you die soon enough.
