No, it would be near useless for the most part. The Tiger and Partner would be far superior for typical AH use. And due to it having such a slow rate of fire, the one thing it might theoretically do better at (long range sniping) would be excessively difficult.
Beyond that, the Jagdpanther's 88mm, available for a mere 30 perks, would tear through it well beyond 3000m, and it would have the optics to reliably put it's shell on target.
Before we get the IS 2, we should get some of their TD's, the SU 100 in particular.
