Torn between Engineering or Enchanting to go with Alchemy.
Leveling an Ele/Resto Shaman on Horde side at the moment, starting with Herbalism to train Alchemy along the way. Once it's at 450 and I'm well stocked on Frost Wyrm Flasks, Wild Magic Potions, Rejuvs and have the Endless Health/Mana and North Flask, I'm going to drop Herbalism in favor of something more optimal. Originally I was going to go for Enchanting as it would be the most straightforward, but Engineering is making a strong case with some of its enhancements where regular enchants wouldn't benefit either build otherwise, namely the boots (Crit rating is the only stat I can get that helps either spec), Spellpower for the Cloak, and the Haste clicky for the gloves.
My Prot Pally has mining so it would just be a matter of time investment to acquire the materials for Engineering. If Engineering is the better choice here, do I go for the Frag Belt or the Pulse Generator? And most importantly, does the 25% Engineering bonus from Health/Mana injectors stack with the 40% bonus from the Alchemist Stone trinkets?
