The HOT meta events.
The meta events can easily be done with a party of players.
For VB night meta, you generally need at least one player per camp although there is a buffer. The night bosses can each be killed with a party of players who can break the bars.
For the AB octovine meta, you can technically do it with a party at each side. You just need people to know what they’re doing and not AFK on the sides between DPS phases.
For Gerent, most people tend to aim for 15 per lane. Theoretically you can do every lane with less than that other than Nuhoch as they tend to have easy events. I’m not sure how the scaling is with only a few people with the spores at Nuhoch but I doubt it’s pretty.
For DS, while it’s probably possible to do the escorts with a party of players in each lane, you’ll never beat the blighting towers. You’ll typically want a full map.

Group events are generally balanced for 5 players and scale for 3+, so the metas are balanced around 20 people in total. Keep in mind that scaling wasn’t designed to keep up the challenge, only to keep the content relevant, hence the easy mode zerging.
They should really put the minimum scale on events instead of just calling them group events.
