pvp 1 button damage for resto

Hi all

first of all i would like to say i love the site and the support from everyone. I am trying to find a 1 button damage macro that i can use in bg’s to eliminate having to use several precious bar spots up. I am running a pretty cookie cutter resto spec. not looking for anything fancy just something to help when team is bursting down and not in big need for heals.

thanks in advance

/console Sound_EnableSFX 0
#showtooltip Lightning Bolt
/castsequence reset=combat Flame Shock,Searing Totem,null
/castsequence reset=0,3 0,0,0,lava burst
/castsequence reset=0.3 0,0,lava burst
/castsequence reset=0.3 0,lava burst
/castsequence reset=target lightning bolt,flame shock,lightning bolt,lightning bolt,lightning bolt,earth shock,lightning bolt
/castsequence reset=combat searing totem
/cast [combat] Ascendance
/targetenemy [noharm][dead]
/script UIErrorsFrame:Hide();
/console Sound_EnableSFX 1

this is what im trying out now please advise on any thoughts towards changes
