^^^ Correct. DONs are low variance compared to other games which is why they're so popular as BRM builders with recreational players (which also provides a target-rich environment for regulars).
DONs require a different strategy and not everyone has the stomach for them. Personally, I love them. Especially the 6-max DONs, but unfortunately Merge dropped them. Most people play way too tight and can easily be exploited, especially near the bubble and as stacks reach push/fold levels. If you're on a winning stack (top half), avoid risk near the bubble -- if you're getting short, leverage your FE before you get too short and push aggressively until you're over that magic 3k threshold. If you can accumulate and maintain 3K you're a guaranteed win regardless of what anyone else does. OTOH if you're near the bubble with a comfortable but not huge stack, learn to fold big hands like KK/QQ to the the small stack shoves that are usually shoving any ace. Some folks will even fold AA here to avoid the 20% chance of losing a lock on the win.
I first tried DONs when Stars was offering them, and went on like a 20 game winning streak which is probably what set the hook for me. This year I made ~$4k (including RB) in about 3 months 4-tabling 6-max DONs each evening after work, mostly the $30-$80 buy-ins. Sometimes just playing 4 in a session, sometimes 16-20. I just didn't want to put in time and volume post-BF, and DONs were immensely profitable for me given the small amount of volume I was playing.
I hold my own in regular SnGs but for whatever reason I was drawn to DONs and seem to have a knack for them. Hated like hell to see Merge drop the 6-max ones -- after playing 6-max, the 10-max ones are excruciating. I hear Cake still has 6-max, but I always hated Cake back in the day when Sportsbook was there. Maybe I'll signup for a Cake account for CC events and check them out.
