What classes are currently broken? example monk classes no flurry of blows work as intended.

If you ask about stuff that doesn't work properly:
Monk AC works with shields
Crane Wing/Riposte works with 2h weapons
Flurry works with dual-wield(but not with shieds)
Monster Tactician doesn't give summons team feats
Items count to qualify for feats
TSS passive doesn't reduce skill penalties
Duelist precision damage still applies to every element that is not a part of a damage roll. EG alkali gloves, geniekind, bane and so on.
Think that's the most of it. Not too bad, compared to what it used to be.

I may have misunderstood what you mean but at least for me MT:s summons (levels 1-3 tested) do get at least outflank and precise strike. Are there some other team feats or summons that do not work?

I tested it just now and it works.

Well scrap that from the list I guess. I'd still take conjueror or cleric over MT any day of the week but at least he now works.

It works but the inquisitor needs to be flanking with the summons to share them - aka only the summons you are flanking with are getting precise strike and outflank, which is still kind of a shame and not really what the tooltip leads you to believe. But yeah, not being able to have multiple summons out and no transitions towards late game spellcasting is too big of price to pay imo. My main gripe with summons is that they do not get buffs from bard songs, and I assume won't get the buff from freebooter either (maybe they'll get freebooter's bane at least?). Not sure how it's supposed to be in PnP.
