I think you need to seperate your totems from your casts
I think you need to sperate your totems from your casts.
I use all 4 shaman have all out dps on button 2
/assist focus
/castrandom lightning bolt,flame shock,lava burst,chain lightning,purge
or
/castrandom [target=focus-target] lightning bolt,flame shock,lava burst,chain lightning,purge
and on button 3 I have my resto shaman healing my pally and all of the other shaman still doing the same all out dps so span between button 2 and 3
/cast [target=focus] earth shield, (the heal over time one), lesser healing wave, chain heal, ....
as for totems, I control them from my numpad keys with numpad-5 being my panic button chain heal from all shaman on themselves ( /cast [target=player] chain heal )
you will have to decide your own totem patterns but I have numpad-1 as being all healing totems and ( 7 & 8 are different sets of pvp and pve totem cast squences )
I use xperl and it allows me to bind my numbpad keys to any set of bars, so I setup BAR-5 to use numpad 1-9 in the first 9 positions
The problems you see at the very lower levels is that shaman are under powered due to no mana pool and bad gear. they will be much more powerful at 60-70 range.
