Hi. I play a hybrid warlock(SL+dmg talents) with 30k+ lifetime kills on 29. also played a lock at 70.
Hit rating:I use 11hit rating necklace as a hybrid build. Suppression for Affi build imo. I feel one of them is enough but you will miss often without them. If you are always with a heal-bot or dont care about miss(loss of gcd/mana) you can skip both.
Talent:I suggest you to play Full Affliction with Full DPS gear set. and try several Tank builds with Tank gear set. then Mix them for your hybrid build. I dont know your best balance between DPS/HP/Reduction. personally for solo pugging, around 1500hp is minimul without SL. You can go less hp with SL and other reduction talents. I switch gear set for more Sp when I get buffed.
Pet and talent:You better pick one of pets that you use. then spec for it. VW for Glasscanon build,Succy for Tank/CC build imo.
Glyphs:I use Corruption all the time. Surprise burst is always good to have. SL talent itself works just fine to me. I'll take demonic aegis over SL glyph if I need more reduction(about 1% phisical reduction/point and some healing bonus).
Gear set:My core sets with buffs are DPS(230shadow,low hp),Balance(180-190shadow,medium hp),Stamina(120ish sp,high hp).
Hope this helps.
