I find it quite strange that Survival spec has no self healing abilities, despite its name and supposed specialization.
Beast Mastery has Spirit Bond and Spirit Beast's HoT ability.
Marksmen has Chimera Shot which gives 5% max hp on every cast.
While Survival has absolutely no self healing capabilities, which just reeks of bad design - especially considering certain other classes (Rogue, for example) got decent self healing abilities in Cataclysm.
Self healing is quite important during Leveling, as well as in PvP where even a small heal can mean a won Arena match or a captured BG objective.
It can also be quite helpful in Cata PvE raids where Healers mana is supposed to matter a lot, so every bit of free self healing counts.
So, what do you fellow Hunters think - why Survival has no self healing what so ever?
Edit:
Beast Mastery has quite good defenses and a superb tanking/utility/dps Pet, and Intimidation 3 second stun.
Marksmen has constant Daze on Chimera/Multi, and has improved Disengage, and Silencing Shot and Readiness.
Survival has improved traps, Mirrored Blades and a Sleep sting which breaks on any damage.
To me it seems that all 3 specs have about equal "control/defense", which still leaves the question:
"Why does Survival has no self healing?"
