Not sure what changed, but on my side the item lag appears to be completely gone, but asking around I get mixed results. It looks like some are still getting it. On the other hand, the rate of spamming hp pots seems to be much lower, so I wasn't able to survive vs mobs of my level.
Come to think of it, if the price of the Special HP potions were higher (10x the hp, maybe 15x or 20x the cost, not 30k per potion), that'd probably make the game much more enjoyable, and reduce the item spam quite a lot with 1 easy change. Or make VR available to all classes.
Edit: also not having c-grade armor at lv 73 would probably help too.
