One thing that I somewhat didin't understand was the ending. Why in the temple? Why not the Venatori stronghold in the hissing wastes? This ties in with the whole every zone should have been tied more to the mainstory idea. The venatories last stand was a bit lacklustre. This may in part because of the last gen limiting the number of enemies we could face at the same time. That situation has clearly changed now as seen in the Descent.
But anyway after Pride I would have preferred a manhunt for Corys hideout wich would lead us to the Hissing wastes, explore the wastes in search of the stronghold. Some war table missions like in the approach, plains and Emprise to reach it and end with an assault like Denerim/Adamant etc.
Only a guess, but it may have had to do with the position of the Breach, as Cory was ripping it open again. This was close to the Temple.
I'd say that this is right, since he's technically re-opening the original breach.
However, the SH assault thing might have been fun. The only real downside is that we pretty much decimated his forces in the Arbor Wilds going to Mythal's temple, what's left of them anyway. So either way, it might have ended up pretty much like it did anyway.
