Yep, that's right. My Gnome Rogue hit 70 and that makes Number 16 for me. And all without the aid of heirlooms or 'refer-a-friend'. Uh yep, I have a lot of time on my hands.
Who will be next? Well, I am working on a Warrior who is level 33, and a Priest, who is level 34. I just can't really get into playing them though. Knowing that at max level(and even now) they are EXPECTED to be THE tank and THE healer is annoying I suppose. Probably what holds me back most as a soloer. Since I have no interest in grouping at any time, these two classes hold the least amount of interest to me. And they are still really difficult to level at this point. But then I suppose neither were meant to be leveled solo which is why it is so tough.
My next highest characters, as mentioned before, are hunters and rogues-which are also the last two classes I got to level 70. Maybe it's time to go back to my leveling my Nelf Moonkin who is 71.
One other note: my rogue dropped skinning and took up Jewelcrafting. I farmed every single bit of my mats, and by selling the items plus the extra mats, I've made over 1500g this week. I've been limiting how much I actually put on the AH at a time so as to not flood and still have loads extra to sell. And after finding some that don't sell, I send those to an alt to disenchant. So his jewelcrafting is currently at level 342 with only a few points to go before starting Northrend materials.
