Why nobody plays a lock anymore, as written by a lock

I went from absolutely loving Demo when I swapped to it when ICC came out and it rocked for the 9 months we were stuck in there. Originally I only went Demo to stack spirit and buff that raid as much as possible, but it turned out it was pretty awesome. Molten Core procs were plentiful and often. The Princes in ICC was the greatest, you could maintain a near 100% Decimation up time just bouncing a SB at whichever prince was at 1% hp. Nobody could touch my Demo lock on that one, not even close. Soul Fire under Decimation used to hit like a truck instead of the wet noodle it became in Cata. I'd be 4th or 5th down on the meters going into execute phase, but those SF nukes hit so hard I'd often climb my way to first in less than 25% boss health.

Then Cata dropped a big ol poop on Demo. The spec just seemed like it wasn't working right this whole expansion and they just never bothered to do anything about it.  All we got was another slow-cast nuke in HoG who's main benefit debuff was often negated by the tank or boss moving. Most Demo locks were and still are confused over whether Shad Bolt or Incinerate is supposed to be your filler.  Tier 11 alone saw Demo's using everything from the Succy to the Imp for our main DPS pet depending on the patch. In fact the one pet we haven't used this whole expansion for pure dps is the one only Demo's can use, the Felguard (Blueberry doesn't count). As things normalized heading up to Firelands we got the whole Felguard/Felpuppy/Demon Soul/MWC pet twisting dance, which maximized dps enough to justify doing it, but in reality few locks could master. Not to mention this whole set up completely voided our other main new talent, Impending Doom... "Oh my Meta is up but I still have 35/25/whatever seconds left on my Demon Soul and trinket." What a friggin headache.

In addition if you didn't have an Ele Sham in raid your GM or raid lead would probably be pressuring you to go Demo whether you liked it or not.

Oh and Gul'dan help you if you didn't have this shit down pat, your dps greatly suffered, even being off a little. There was no, "Oh I missed that cd or that HoG Immo refresh on this rotation, I'll get it next time and keep going." No, you were screwed, there was no recovering and keeping up with everyone else.

And your reward for mastering this nightmare of a sitation and pulling it off perfectly? Roughly about the same dps as that shad priest or mage or hunter or any other class who doesn't have to track of half the timers you are, doesn't have to hit a forth of the spells you do. No wonder nobody plays this class anymore. Oh, and only if you didn't have to move too much and could stand in melee the whole fight! Frig that!

Destro is the only spec that's felt right this whole expansion, which is sad cuz you should have just rolled a mage if that's what you wanted to do. But Destro made sense when you looked at it, you weren't scratching your head over the spells you were using, the procs and flow and rotation/priority and ISP getting better and the use of Soul Burn in execute phase plus Bane of Havoc! All the new stuff weaved perfectly into the old standard stuff. Destro is and has been great symphony of a spec this whole expansion, don't know what went wrong with the other two.

Affliction got better once we no longer had to deal with the whole Improved Soul Fire talent/buff. Affliction locks juggling Soulfires? That was just wrong! Then they nerfed the hell out of our only cool new ability Soul Swap (for PVP reasons I'm sure, which is just pouring salt on the wounds) and SS still requires a glyph for something it should just do by default! Soulburn Seed? Oh please... 1 fight currently that comes in handy and still doesn't touch the aoe of most other classes even when combined with a Shadowflame. That's locks using a CD, and 2 separate aoe abilities, not even coming close to Mind Sear, Multi-shot, Swipe, FoK, etc... so on... Oh, btw here we are a year later and Affliction locks are back to using Soulfires because of the tier bonus!!

*sighs and hangs head dejectedly.

Any more confusion over why locks are the least played class?
