I use a clickable trinket during my EM+LvB instant nuke, which gives me 440spellpower per shaman.
Gloves: 28spellpower
JC/Ench: 46-49 spellpower
Trinket: 440 spellpower (Not to mention they could release a 800sp trinket in the future, never know)
With Engineering, you are giving up 514-520 juicy SP. I've done some target dummy testing, and that extra spellpower boost causes an extra 1100-1600 dmg on lavaburst alone. This spellpower ALSO scales with the clearcasting bonus, which the rockets do not. Not to mention all the other spells I cast during those next 19 seconds get the boost as well... which is huge. For LvB alone, rockets will do slightly more damage... but all damage combined, my setup gains 500% more dmg easily.
Either way requires leveling a profession, which if you are serious about arena you will anyway. I just want people to know engineering is NOT a must... and Ench / JC provide a nice means of making cash.
