WoT Supertest: Second Iteration of SU-122V

SU-122V (USSR, TD-9, premium mechanic: siege mode via hydropneumatic suspension activation by button) — changes relative to update 1.28.1 base.
The second iteration of the SU-122V appeared on the WoT Supertest yesterday.

The vehicle received an almost complete rollback of previous changes, with some exceptions, following its transition to Tier 9. Its characteristics have largely returned to those of the first Supertest iteration (link). Notably, the Siege Mode offers very few advantages beyond hull tilt and reduced dispersion from movement and hull traverse.
