I don't think there are guilds who have killed Kromog since monday, unless they have done it without melee players (even if they have a place where damages are too low), and like you said, for a heroic boss, it's driven to abuse for that
Up,
Slam needs a fix, the hotfix of this week made the boss really hard to kill especially on the Frenzy phase. I really don't know why you didn"t keep the script of last week.
