Rev Line of Sight problem (DM)

Rev: Renegade- shortbow x2

Could just be me but my line of sight (or any distance skill) is obstructed very often for absurd reasons. The occasions include such things as ambient creatures or an ever so slight bump in ground etc. Had no problem with the line of sight in DM until a few days ago.

Incidentally, my ping when first doing a x5 DM was 215rtt (WC OZ). Swap straight over to HOT maps.. a 5-6min wait on load and then a 970rtt. Back to DM-225rtt. Immediately go wvw (loads ok), then.. yah! 1340Rtt. Over past 3 days, the DM has got worse av 340 now.

Having said the above, over past couple of months my av rtt has decreased by 41.87%. HOT maps are however, for me, a waste of time. Av rtt 1100

Just an FYI
