[EVERYTHING] Is Dany's army still...

at as much of a disadvantage of that they are portraying it to be?

At the end of the second episode, the Greyjoy's fleets go ambushed and taken out. They lost a significant amount of ships and the leaders of Dorne. Yes that sucks but that doesn't mean all the Dornish armies are out of the game. What of the secondary houses? There is obviously someone second in line to take up the reins of Dorne. It should give them even more vigor to fight the lannisters.

At the end of the third episode, the Lannister army leave the westerlands to attack the reach and the tyrells. Yes, that sucks that you just lost the grains and supplies of the reach but is it the best? The lannisters just lost Casterly Rock. Even though to Jaime and Cersei it's nothing but a memory, to everyone else I'm sure it's much more. The bulk of the lannister army is in the reach and they just left all the westerlands undefended. As like for the Martells, there are many subhouses that still have their homes there. What's going to happen when the lannister army realizes that their homes and everything are slowly being taken over? Aren't they getting supplies from other parts of the westerlands? It just doesn't seem like that smart of a decision to just uproot everything mobil and move somewhere else. There are definitely establishments, more than just the castle of Casterly Rock that are important in the westerlands that the reach can't simply replace. Whether it be supplies of armor, weapons, etc.

I applaud them to try and make this war more balanced but still, it seems certain loses can be overcome and other loses can be turned into wins.
