The talent point for level 50 isn't flashy, but it's really handy - you can finish off Improved Revive Pet for 4 second pet resuscitation. You do pick up your second minor glyph slot, and the Feign Death is probably a good second one. If we had gone purely with Marksman talents instead of getting faster pet revives, level 50 is the earliest you can get Silencing Shot.
Skills, Level 50:
- Serpent Sting (Rank 7), Steady Shot (Rank 1), Track Dragonkin, Volley (Rank 2)
You also get Dragon tracking, which will be useful if you quest in zones with them, or if you want to farm for whelpling pets.
