Some questions for someone who is noob at lock.
I see levelling builds all over the web. Could you link a pre 50 build for me? All the levelling builds I see use full affliction maxing lifetap coruption and drain soul/life.
Also don't you lose the lifetap health drain stuff once you go full demonology post level 50?
Here's the talent tree I use pre 50 =
http://www.wowhead.com/talent#IfhrbdrhoVZbGc0o
Basically I put my talent points in those spots to do the following for smoother botting:
-Gain some Stamina (helps survivability during bad pulls and more HP is always a good thing)
-Make my pet stronger and more effective (being able to take more damage, kill faster, and hold aggro better = faster and safer grinding)
-Gain more mana from spells (Less drinking = more time killing = more XP per hour = faster leveling or farming)
-Gain more life from spells (Less eating = more time killing = more XP per hour = faster leveling or farming)
-Reduce my threat so pet can hold aggro (if my Lock is not taking damage he'll need to repair less = more time killing = more XP per hour = faster leveling or farming)
As far as "losing the lifetap health drain stuff once you go full demo at 50........yes you lose the better returns on those spells, but you still have the spells themselves to use. Even at base (not changed through Talent) they are very effective spells. After I spec demo at 50 I just usually start grabbing those Affliction talents on my way to 80 anyhow, so once at 80 I got a great farming pet, and the increased Affliction spells. That combination makes for a really smooth and fast farm bot.
One thing to keep in mind is that these talents alone are not going to make your lock a better bot without a good warlock CC, proper CC configuration, and a well written profile. I use the skiWarlock CC and think it's great for what I want my bot to do.
