Yeah, this is pretty normal if you are leveling faster than you can gear up. If you're really worried about it you can always buy some vendor gear or check out the MB to fill in the slots you are in serious need of upgrading until things level out, but if you are beyond lvl 50 and are still in lvl 50 content you will be fine until you reach HW to gear up. Or SB. Whichever comes first. lol Thankfully Poetics will be raining from the sky at lvl 50 so you can always buy gear from Mor Dhona's vendors or from Idyllshire if you wish to wait till lvl 60.
