You're probably going to lose money. The prices will continue to drop until the update comes out, then they might have a small amount of positive updates before stabilizing. Imo your only solid investment was in the rocktails and maybe the DDs.. The javs/axes you might get fucked on because for all we know Jagex is going to make PVP items easier to obtain than they currently are.
Can't take a little criticism? Cry moar.
