Before I proceed I must tell you
a) I am a casual
b) Never stepped foot into Normal or HCs...simply because I did not have time commitment for that.
c) I am currently stationed in Bangalore,India and my lag time is around 450ms to 600 ms.
d) I am a pure destro (main/os) from lvl 10 - 90.
Though embarrassing I must admit that I don't even know the spells of the other two specs having played this lock from Jan 2, 2013 only.
My toon : http://us.battle.net/wow/en/characte...4uron/advanced
Having said all that, I was pleasantly surprised to do see my spec do well in LFR though ppl everywhere (wow forums/mmo/guild/trade chat) asked me to learn Aff for raiding
^ As you can see I scored 2nd in damage in LFR.
^ I scored 100k+ dps on this LFR.This was my first time breaking 100k mark (even higher in dmg done than 491 ilvl demo lock behind me...though he had better burst)
Only thing I did was micro-managing my embers/dark soul/havoc
TLDR...destruction is not that bad for raiding
PS : Would I have scored more dmg had I played Demo/Aff with my gear (and the same love that I have for destro) ?..Dunno
