Spent few nights on the ptr, trying out all specs, and I must say the most fun I had in bgs is with affliction and GoSac. Currently, I am running 1211332 and spreading my dots all over the bg. Hilarious results.
Demonology feels like the strongest non tank 1v1 spec on the ptr, or possibly weaker only to the assassination. Play style is quite interesting, and with dark pact and demon skin you are invincible. The difference between Demo and destro/aff is that you retain stun from Felguard, another stun (or interrupt) from GoServ and with empowered felguard you have stronger dark pact shield. I kinda still didnt find the best possible "dps rotation" for battlegrounds, and I kinda cant keep up to shadowburn destro and ofc the affliction in dmg. This is due to me not playing optimally, and because people can easily outrun you if you dont have all the cds. Summoning entire legion of demons just to see that monk run away feels bad every time...
Also, wanted to touch on my idea for a destro pvp spec. Now the other day I watched cobrak's video on destro chaos bolt spec, and was kinda sad to the result. Cobrak, the famous destro lock youtube-er, pointed out some real issues, and problems of the spec, but besides that I realized one thing. When he used his firestone, his chaos bolt dmg doubled. Now to me, as a mathematician, thats str8 up a stupid thing, I mean he has some baseline crit % from the 850 ilvl pvp estup in bgs. This means he somewhat reached his crit lvl (which is more than zero)+100%, which is more than 100%. Dumping maths behind me, second thing I realized is that destro can, again mathematically, 2 shot people. I would really like for some1 to try this out. Whats the deal?
Well, you go for firestone, Initiation and curse of fragility. You curse of frag a target, conflagrate (target is over 80% most likely. confla dmg is shit without the artifact proc)>firestone>two chaos bolts. Cobrak's chaos bolts were hitting for 480k with firestone active, and 240k without. Simple maths will tell you the following, with addition of initiation chaos bolt would hit for ~529k while firestone is up. Thats over 1 mil dmg. What next bothers me is haste ratting in bgs, and casting time of chaos bolt (on Ptr with backdraft i have a 1.5 sec cast time on it almost), and adding soul harvest to the equation. With soul harvest, dmg of single chaos bolt goes to ~662k, which means 2 will hit for 1mil and 324k, curse of frag lowered targets hp to 1m and 600k alrdy that means you still have some 4 sec of it and firestone to deal those <300k
I know this is all maths, and theorycrafting, ofc first question is who in their right mind would let you do the whole process while watching, but I would first like to see if my theory is correct. I dont have Beta access, I am kinda tired atm and my spelling is going nuts. 2mrw I would like to discuss the possibility of using succubus as destro, with sacrifice and dark pact along with casting circle as a means of setting up this whole burst. That would be my first idea of how to make somewhat take that full combo... Hope my maths is correct and some1 can try this whole thing I came up with during my preparation for ring and field theory. Thats where I got the idea to use casting ring
EDIT:tried to format it a bit... TL DR Have a neat idea for destro spec, some1 pls try it out on beta. Enjoyed aff the most in bgs, its amazing on the ptr, while demo feels clunky and sluggish to me.
