User blog comment:Erenz/Stop Leeching in Kielazar Raid!!/@comment-26140304-20161026040826

To be honest, if I can defeat the boss, it's more power to me that I have people leeching in my rooms. Leechers receive very little benefit other than the completion of the quest because they don't contribute at all to the quest. It's not good practice for leechers, but that's what they get for doing so.

If you know the enemy patterns and you have a good squad fulfilling essential buffs, then the raid boss shouldn't be much of a problem. Later down the road, we'll look back at this boss being easy with newer units coming out.
