So my opinion is kinda the opposite of the above, i find Hydra's easier to read, because generally speaking, you can focus in on one head, they still have all their tells, they are just more flipfloppy on their reads because they do have someone they can fully trust also giving them reads.
All this of course assumes that they are actually signing their posts like they should, but overall I think it actually makes it harder for the Hydra to hide as Town/Scum.
That said, i also don't think the above is good for the health of the game overall, and (slightly tangential point here) given the lack of games already running, they probably should be mostly shelved, as it's already relatively hard to get a game running by the looks of things (at least that's my opinion from having returned recently)
