hi

what are the class and spec with lowest amount of keybind?

i'm playing hunter on icecrown and pvp is hard coz of big amount of keybind :(

i'm interested into:

lock

priest (sp and heal )
drood (feral or heal)
shaman (amelio or heal)

Frost DK.

Rotation goes something like this-
Howling Blast - Plague Strike - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate - Obliterate

I think Ele shaman.

Purge, 3 spell casting dmg, 3 shocks for dmg, 1 shock for interrupt.
1 spell for healing (u can ignore chain heal or long casting heals).
1 spell for CC (hex)
Totems + wolf + buffs

In Arena, purge targets, dmg dmg dmg, root ppl, dmg dmg dmg, root ppl, dmg dmg dmg, root ppl, dmg dmg dmg, root ppl. And heal urself if needed :)
