FYI
Now that my hunter is about halfway through Cataclysm (lvl 83) I thought I'd report my experience for anyone who digs up this thread looking for info:
I leveled 1-51 as survival. Explosive shot + 1-2 autoshots took out everything before it reached me. I generally alternated between explosive, and 2 steady shots. Especially in the lower levels (before sprint, boar's speed and charge) I generally killed everything before my pet even reached it (making it better than BM).
At 30 I picked up MM (dual spec). Aimed shot was pretty good, but not instant cast, and it generally felt more sluggish than survival, although this may have been an illusion from the cast time. I stuck with survival until 51 (rapid recuperation).
At 51 I switched to MM, and killed everything with arcane shot, finishing with KS when possible. chain killing became super fast. It became even faster at 70 with the addition of chimera shot (use it to open when off CD), and even better with MD at 76 (+glyph, open with MD to pet macro:
Code:
/cast [target=pet] Misdirection
/petattack
(PM me if you are interested in the more advanced MD macro I use)
At 80 I went to Hyjal. MM wasn't quite as good as it had been because I would burn all my focus on AS spam, and the target would still be alive. However, once I picked up some better cataclysm gear, I could resume my regular MM rotation. At 83 I am chain killing everything very quickly, and as long as I'm not fighting more than 2 things at a time, mend pet (+glyph) is enough to keep my pet alive.
One last thing: this was with full set of heirlooms, scopes, and highest available elixir (of agility) or flask. This advice may not be optimal for non-twinked characters.
Hope this helps!
TLDR (bullet point tips):
- 10-51: Go survival, open with explosive shot. If need focus, use spam SS.
- glyphs: Explosive Shot, mend pet
- 51+: Marksman, make sure to pick up (2) Rapid Recuperation. Spam arcane shot, finish with KS when possible. Open with chimera shot when available (70).
- glyphs: Arcane Shot, mend pet (both glyphs). KS and chimera shot also useful.
- 76+: make sure to pick up Misdirect + glyph, open with misdirect to pet, see macro above.
