When the character boost to 90 is available, there will be a shitload of new characters. I think that most people who are currently playing will pre-order WoD; why won't you want a free level 90? There will literally be hundreds of new 90's as soon as this is available.
All these new characters will need all kinds of stuff, PvE gear, PvP gear, enchants etc. Which professions will in your opinion benefit the most by this huge can of fresh lvl 90 characters?
Things that I think will be in high demand:
- Glyphs. Everyone will need them
- 476 PvP gear. Before going into BG's to farm honor people will want to have a PvP set.
- Enchants /Gems : enchants / gems probably will see a rise in demand as most people will want to enchant/gem there Timeless Isle gear. I'm not sure many people will go into the depths of LFR this late, but almost everyone will get a set of Timeless gear.
Anything else? Are you going to do anything to prepare for it?
Edit: Woops, mistakenly used it's instead of its in the thread title. Sorry!
