That last comment applies to a lot of monsters in the series if you think about it; due to the multiplayer-focused nature of Gathering Hall Quests, the monsters tend to be challenging when fought alone due to them having only one target to focus on and having higher stats than their offline counterparts, and anticlimatic when fought in a group due to there being more targets for them to focus on. There are exceptions, of course, but this is how it usually goes.
