It’s because the WWBarb isn’t fast enough. In my experience, WWBarb isn’t that good solo with this type of event, since you need 350 kills and as you said they don’t spawn fast enough.

Only one major event spawns in that area so just keep restarting the game until you get it, it won’t take you long. Meaning if you see another event like Burning Man or Lord of the Hill, then you won’t get the Cursed Peat in that game. It’s usually pretty close to the waypoint and it’s one of the exclusive-type events. However, it spawns in-game as a non-bounty far more often.

It occasionally shows up as a bounty, but it’s rare. Fish for the Cursed Peat event in Paths of the Drowned, Act 5.
