Survival is the spec of choice these days thanks to the buffs it received in 4.3 and 4.3.2. This means that the spec is receiving closer scrutiny than it has in the past. The consensus build appears to involve SV taking three points in One With Nature, two points in Sic ‘Em! and none in Careful Aim. However, often left out of talent discussions is how this build’s optimality is conditional upon pet talents.
Edit: Post updated to include Frenzy builds. Thanks to Harvoc for the suggestion.
