I don't feel the airplane is as overpowered as much as the sidestick just seems excessively sensitive to pitch inputs during rotation.
Several up-close PFD videos during takeoff, specifically VR, show the ground roll guidance cue at 10deg pitch-up, with a very slow pitch response from the airplane. I've noticed if I put the ground roll guidance cue at 10deg on the ini A340, the nose wheel hops off the ground aggressively, nearly causing a tailstrike regardless of takeoff performance settings.
Overall though, excellent airplane. I love it, and can't wait to see where ini takes the product into the future.
