Less experience from fighting many weaker monsters than taking on fewer more powerful ones, yes. That's not hard to rationalize: you learn more fighting 6 different monsters, each of which is much more powerful than you as an individual, over the course of the day, than you do fighting 18 of the same monsters, each of which is individually less capable than you.Something I've been thinking about in 5e: I've been DMing pretty much since the outset of 5e. During the process of encounter design, groups of monsters get an effective "XP multiplier" that counts toward encounter difficulty and XP budget; but does not contribute to the actual XP earned by the PCs. The ultimate significance of this is that larger encounter groups are worth decreasing total amounts of XP. And, given a trend of more or less balanced encounters during a play session, the PCs are likely to earn LESS experience the MORE monsters they fight.
But, it's mainly an artifact of Bounded Accuracy: being outnumbered just really sucks in 5e.
Agreed.I've got mixed feelings about this. It conveniently enables DMs to speed or slow experience gain as suits their preference. But I have also occasionally had frustrated players who were unimpressed at the XP gain at the end of a session in which they vanquished many foes.
