What is the best tradeskill for multiple toons in MoP?

Leather worker is great to have, the pvp items sell for lots all through xpac.

JC will make loads of gold at start of xpac, as gems will sell for very large amounts, especially now its a new xpac and new Raid Finder... for loads and loads of people to get through for some time and then all alts, and alts of alts as well...

Im just going to hammer the inscripting as ive planned for it, to make an extra tonne of gold with DMF for a while, then maybe slowly sink back into prospecting and deing x5 if i feel i want/need more gold. Overall be to busy at start levelling main, alts and a herber, farming, gearing and doing it all over again slower on rest of the scrub toons :P

I'm having all my characters get max engineering because the new stuff coming out looks just damn fun, and having the ability for a paladin, shammies and a priest to go invisible is nice, too.

Invis? WoW! Stuff like that normally cant be used in BGs or gets uber nerfed somehow. Is eng getting new mounts this time? i know the JC mounts look bad ass!

I was thinking of making my 5 Alchs> JCs as well...but might make them eng. and one of my other teams all JCs+eng
