Klepar Hahaha, yeah. From my experience, there are like 2-4 girls in a top guild that does raids and endgame competitively on average. In some novels, half of the guild's best players are the MC's harem.
Also, I wish that a novel would have a good guild system and fair item distribution. In most novels, you can already guess who will get the item depending on its rarity, especially if there are like 4-5 players that could use it and the MC isn't one of them. Then one of the MC's harem gets it for sure, the more liked she is the better the chance.
A normal guild would fall apart after a couple of such runs, and these people keep doing it without stop.
