So I finally managed to hit level 90 on my alliance paladin on Sunday, giving me 16 in total. Not many compared to some, but I'm pretty happy with the total all told. It's interesting that is really only 3 more max level characters than I had at the end of Cataclysm and one of those is my boosted character from the pre-order.
That leaves me with 6 more alliance characters that are still in the leveling process, and all of those are sitting in the mid-50's (except for the monk, who is in the mid-20's.). Despite the lack of focus on leveling new toons in MoP, most of those same alliance toons were in the mid-30's at the end of Cataclysm, so I did make a little bit of progress on them.
I'll probably continue to work through them all a little bit between now and when Warlords drops next week, in addition to my gold making efforts.
I'm still finding that most of the old standby professions from MoP are still producing decent profits. For some reason, people on my server are still continuing to buy crafted PvP gear, which I don't understand at all, but as long as people keep buying it, I'll keep selling it. Glyphs aren't selling as well as they did before the patch given all the changes, but it is still a dependable source of income. Enchants continue to sell extremely well. Gems have tapered off a bit after the immediate post-patch gold rush - they're back to around the same general level of profitability that they were.
So my banks are all cleaned out, my reagent tabs organized and filled, my toy boxes stocked. I have a few odds and ends pieces of gear that either need to be sold or put into void storage, but by and large, I think I'm ready.
I was debating running around collecting additional bags for my variety of toons for leveling, but for some reason, bag space has never really been a big issue for me while leveling. I tend to ship things that need tending to off to alts at the first available mailbox, vendor things regularly and keep a ready stream of disenchanting going. Assuming a lot of the random crap that you tended to get in MoP will now be toy box eligible and that there won't be zillions of random food items for your farm dropping like they tended to in MoP, I anticipate it will be far less crowded than it used to be anyway.
Most of the times that I had bag space issues tended to be if I was trying to assemble multiple gear sets, but I don't anticipate that being as much of an issue this time around as it used to be given the changes to stats brought by the patch.
That being said, I may go grab a quick Onyxia bag and Grummlepack on most of my alts as those are pretty easy to get.
