I've been having that problem a lot too since the patch. I've also been caught up on objects a lot (like the Summoning Bell, can't summon my retainer or move away from it) and sometimes I can't dismount my mount or my action combos fail to light up. Mobs don't appear to take damage, players don't gain health from heals. In short, some of the worst lag I've ever experienced in a game. It sometimes destroys the ability to group because players who are currently not having a problem like to think you're just making an excuse for sucking.

But NPCs are taking longer to load, sometimes I actually hover in the air after I dismount my mount, and if I'm DC'ed for too long, not only do I miss out on end of dungeon rewards that I've worked for 30 min to an hour to get (tomes, commendations, duty roulette bonuses, etc.) but I find myself with the 30 min penalty timer.

All this could be on my end except my system and connection have been fine (for the most part) up until the patch and this kind of thing is happening much more frequently now
