The visitors rubbed salt in to Gillingham's wounds in first-half stoppage time as Jermaine Easter slotted home but the hosts equalised against the odds through Andy Barcham midway through the second half as the game finished 2-2.
"I'm really pleased, it was going to be a test for us, even with 11 against a good MK Dons side," said Stimson. "We needed something from the game so to get zero would have been a massive disappointment so to get one point was OK."
On Oli's red card, Stimson added: "To lose a player who's really on form to from what I've seen was a bit of an indifferent decision was tough. I think it was a harsh sending off and Dennis is distraught because he's just got himself into a bit of form.
"It was very slippery for the second decision and sometimes you wish the referee might take that into consideration."
