Check your connection quality with Pingplotter or similar software. Routing issues can cause rendering issues. (Can't wait to get the house finished and onto our much better ISP). That said, I have had the Reduced Awareness notification pop up (not quite 100% with visible connection issues) and some rendering issues anywhere in the world. It hasn't been enough to adversely affect game play; but I am looking for it and will /bug it when it happens to me in such a manner that waiting a few seconds doesn't help.
LoTRO is not the only game that I've had connection quality adversely affect game play. For me, SWTOR is much more finicky about that than LoTRO is.
