1.  first mid you all stayed in your corner by healthkit.  you have to spread out and not let them take control of the mid point/crates, and bunching up by healthkit or any choke is bad since you all eat spam instead of only one person. holding 2 scouts on right need to make sure they don't get too aggressive.  your job is to watch the other team and slow them doing from coming in right, if you take damage then fall back, it is better to run back and get healed then stay there and fight at 60hp.   the roam soldier should be sitting near top of stairs while holding two.  roam should always be in a spot that is more advantageous for him to be in a fight (wherever he has height advantage pretty much).  when you try pushing their two and your medic drops to stickies on the ground, it is better to pop just going in than waiting for someone to take damage.  popping a second early in that situation wont really harm you, and also reduces the chances of dropping to gay stickies somewhere. when holding yard demo needs to make sure he's watching sticky traps he has setup.  both of their soldiers pushed through right and shotgunned all of your stickies before you det them.

2. again on mid neither of your soldiers get on crate, and one of their soldiers on crate just spams down and rapes you.  if you see one of their players up there then one your the soldiers needs to jump up and knock them off.  watching right at two inside you need to always have someone watching the door.  if one of your scout falls back for heals make sure the other one stays there to watch it, or if both scouts need heals then roam soldier needs to come down more and watch it, which in areas like this you need to make sure you com what you are doing so the door is watched.  if you are a scout and are falling back for heals make sure you say it so the other scout can know to stay at right.

3. i'll put it here one last time for emphasis, a soldier needs to get on crate on middle if they keep raping you by sending their soldiers on crate.  also by this round if you see your mids aren't working you should be trying to vary them up a lot more, like going through right or having your medic go up top through right with a soldier.

so in summary!
soldiers need to get height on mid, or in any situation really.  if you are bombing its understandable that you don't, but the pocket soldier at middle should be keeping crates clear.
vary up your middles. if you see your first middle didn't work try something different.  what i like doing with THPS is if we see our middle isn't working then we will keep running different middles until we find one that counters the other teams style.  varying middles also keeps the other team guessing what you are going to do.
don't chase kills/stop going for super flanks all the time.  scouts job isn't always to get crazy picks, especially on granary.  granary is a soldier and demo map, scouts job on it should be to keep track of the other teams scouts and watch flanks.
