Part 2 is the hardest part on dark forest, as mason that is.
I think I can agree with that, even though I don’t play mason as long as I don’t unbalance the teams by joining Agatha.
The masons usually win the map, but when they lose it’s usually on Stage 2. But then again, if they get through stage 2, Agatha is most likely about to lose their royals within minutes.
That is my experience as well, though technically it is a bit strange, since both the Sluice Gates and the Royal Family part is actually very easy to defend with just a tiny bit of coordination.
Problem is of course that coordination almost never happens on pubs (in all modesty I have coordinated a few memorable objective C defences which took a losing Agatha team to victory after 15 mins of holding last objective, but those are extremely rare exceptions).
It is as strange as that first objective on Hillside. If the masons actually defended objective Agatha does not have a chance no matter how organised they are, simply because masons spawn closer. But fortunately for agatha masons almost never defend the actual objective on that stage and thus surprisingly often manage to light the fire by sneaking in.
