I've been having a lot of fun taking my priest through LFG instead of questing. I begun my LFG journey at level 12 and i'm level 50 now after 46 instance runs. Not bad and a lot more fun than the questing grind for me at least.
However I'm a little concerned about when my character hits the various 'gear jump' stages, such as BC, Wrath and Cata. Being purely LFG, my only gear upgrades come from LFG drops/bags. I'm concerned that when I start running the expansions content, for a little while my gear will be quite low considering the quest gear available in those new areas has a big increase in stats. Yes gear will drop for me, but I'm worried for the first few instances I will be quiet down on stats as I won't be wearing any of that quest gear.
Am I right to be concerned? Do I need to explore using tailoring to fill in the gap, or should I have confidence in my LFG blues?
