Talents:
The Warlock has limited options for talents in the 19 bracket. Whether you are going as a “Shadow Rot Build” or the “Survival Build” is going to be the same.
Suppression - Rank 2/5
Reduces the chance for enemies to resist your Affliction spells by 4%.
-Level 19 characters only have a natural resistance of 4%. You should only put 2 points here.
-Corruption Rank 2 has a total of 5 ticks and Curse of Agony Rank 2 has a total of 12 ticks. The latter of the ticks on CoA with more damage. That's a total of 17 ticks for ONE enemy, 34 for two and so on. If you DoT up the team properly the amount of ticks in a 24 second time-span is huge. That 4% reduction is incredibly useful in that context.
Improved Corruption - Rank 5/5
Reduces the casting time of your Corruption spell by 2 sec.
-Corruption is the bread and butter of your dps. It needs to be instant cast.
Demonic Embrace - Rank 3/5
Increases your total Stamina by 9% but reduces your total Spirit by 3%.
-You are stacking primarily stamina with the "Survival Build" You can always convert health to mana so this talent is incredibly useful for both survival and spell casting.
