You're not really going to be missing much. My guys were still replacing newb stuff at 70+. I just the other day replaced the default torches in my charm slots on the 2 80s we mentored up. If you really feel you're lacking, you can have someone craft you gear, the mastercrafted stuff is actually really nice for a long time and some people still sell non-MC gear for the cost of fuel or less. At 70, though, once you hit Kylong, just about every quest rewards you with really nice armor upgrades.

...side track thought...who the hell thought it would be a good idea to put AGI/STR on so many cloth items????
Probably the same guy who rolled an Erudite 'lock like me and found out that picking up 1 piece of plate made him severly burdened :X
