Well from the Bounder's Bounties event, Meneldor seems to be one of the 5 least active servers...I'm on Vanyar, which apparently (and to me totally surprisingly) is the most active one currently. Plus, we're across the ocean.
If you do Helegrod Drake wing to farm some bounties, the whole raid frequently freezes for 5+ seconds if you activate too many dragon eggs at once. It's hard to tell if the server still keeps moving the mobs, but it is very obvsious that it is perfectly synchronous for all raid members, like, everyone sighs at the same moment in teamspeak
It doesn't seem to matter if you have a ###### PC and internet connection or the best you can have...you'll freeze like everyone else.
