This trial is very well designed IMO. Considering we're dealing with dragons and Ishgardians, cannons make a fitting staple in this trial. After all, they've been involved in both Stone Vigils so far. And the fight is also such that high level gear doesn't trivialize the encounter, current difficulty is right on target as the last official battle of the 'A Realm Reborn' main story. Joining a blind party in the PF, my group took 1 attempt longer than a full lockout to down this, so groups with even 1 or 2 veterans should have little difficulty finishing the trial in 1 go.
