Sleeper's Tom Horrendous Lag

[Seipher]

Every time we try to kill bosses, it lags really badly, almost like watching a slideshow. Is there anyway to prevent this from happening? Regular mobs it doesnt lag but as soon as we try to kill a boss, it lags.

any other guild can confirm this? I checked and no lag at all.

No lag for months for us
