I've been taking a break, only playing a day a week to keep up on tomes and the various weekly things. I knew it was bad but today showed me how bad it actually is.
Of all the content I ran, almost every instance I started to lag at one point. At first I thought "okay maybe it's my end?" but a run of Tender Valley showed that the other DPS and the healer were also having lag issues. Had a Normal Raid roulette and a Trial Roulette go the same way (had the game absolutely go crazy because it froze right before the cs bit in the final DT fight, even funner cs when glitched). I went to a few hub areas for custom delivery turn-ins and each time they took longer then normal to load. It didn't disconnect me yet but it's extremely frustrating when the lag makes you play worse then normal.
