With the expansion fast upon us, I'm wondering what everyone is doing with their badges that they've accumulated. Right now I'm relatively badge-poor (about 35), and am afraid to grind out to 75 only to have the gear I just purchased be replaced with a Northrend blue of some kind. Conversely, I'm hesitant to simply blow them on gems as it feels like a waste. Hence, my dillema. Any advice is appreciated.
(and if it matters, I'm pure PvE and recently joined a motivated raiding guild)
