Nope, no need for that. What you may consider doing however is stock up on the required ghost iron bars ahead of time. At least that's what I'm doing, considering the number of new crafting recipes coming in, and knowing prices on my realm are pretty cheap compared to other realms (some of which my server will be virtual realm'd with) I've stocked up on a lot of ghost iron bars for the pet and other crafting. Prices will be insane for the first few days if past experience is anything to go by and I really don't want to be in the position to have to either compete with all the farmers or buy a stack of bars at 250+g just to make the daily combine.
I'm not sure if they're putting in that accelerated bar creation, but if they do it might be similar to the way tailors can make extra imperial silk by using Spirits of Harmony with the cloth. So if you have extra Spirits of Harmony on your engineer I wouldn't be using them up just in case. It might not be implemented that way but I'm holding on to some extras on my engineer since hey, doesn't hurt and if they don't put that in I'll just turn 'em into scopes for all the people getting new bows in the new raid.
