You came a few weeks to late.
With such a low population like on Dyvet there is not much going on there anylonger.
If you ask me it's for the better, for RvR that dungeon is just bad, it lags even on decent machines and all the mob aggro there and little possiblities to move around without losing line of sight makes it not very attractive.
Just got LoTM (finally) and been wandering around the Laby but no action from anyone RvRwise at the mo.
Just seems deadly quiet tbh so is no-one in there .....
....or its me being a spaz and looking in the wrong place?
