As far as I am aware of, no. Players feel it should be a discount, but it has never been disclosed if it is, or it is not.
Overall MO are solid, the consensus is they need a rework to be a proper N5 faction, there is no consensus on what parts and especially how.
MO are the last indulgence of CB's fetish for keeping a tight leash on PanO design space, it's really weird! Every other Pano faction has just been hosed with the buff gun, unlocking all the design spaces that were previously taboo, but MO remains stubbornly janky to list build with. LT restrictions are harsh; you want to take Joan but she's actively a bad LT in MO. She wants CoC, but unlike in Pano your only option is 52pts! She wants cheap irregulars to turn regular, but there's only the warcor. She wants a cheap team with utility to bring with her, but that's in Pano, not MO. Yep, Pano has the best Joan, and the best Joan fireteams. It feels silly, but if you want to play the star of military orders, don't play military orders! :D The Tik isn't allowed to have the LT option it has elsewhere, even tho it's a unit from the military order of our lady of montesa. That's highly counterintuitive, and a shame because you won't see the Tik in MO now, ever. It lost AP on its gun and is only 6pts cheaper than the Seraph, which now completely outclasses it. But, you see, MO isn't allowed any kind of flex when it comes to LT options. If it were, Tik would be the best LT choice in MO, unlike in Kestrel and Pano. Crosiers remain overpriced and without an LT option; I can't think of another line troop in the game that doesn't give you one. Knight commander is the same; tempting but galling at that price and a bit of a trap, when you compare it to a Raveneye or Daoying, etc. Teutons are ace still, but aren't a reason to play MO, as it's ava 3 vs 2 in Pano now; hardly worth gimping yourself for one more teuton. Similarly for the new Crux. MO have had some units get massive glowups, like the Seraph, and the Trin(!), but their long-promised shtick of knight teams remains underwhelming and hard to defend vs hacking. MO also suffers from a chronice case of MA2, meaning that even if you do run knight teams, and do avoid getting hacked, and don't mind effectively giving your opponent's entire amry marksmanship against your knights when they do a wound: as soon as one gets into a f2f with an MA3 unit, they're completely outclassed. MO are now firmly at the bottom of the Pano pile, but that doesn't mean they're bad per se, they have lots of really strong options. It's just that list building remains migraine-inducing, and their best lists will lean on Seraph, Trins, armbots and teuton warbands.
