A few “Italian” answers (please note that this does NOT mean they are coming anytime soon).

- for now, there are likely no other Italian tier 10 candidates apart from the autoloaded Leopard

- Italian heavy candidates are P.75, P.40, P.43 and P.43bis, but the P.40 and P.43 (and their subtypes) are (using German measures) more like medium tanks, the P.75 is kinda like Neubaufahrzeug.

- regarding SPG’s and TD’s, Italians have only lowtier to midtier candidates

A former developer, regarding the testing on supertest (specifically the fact, that in 9.3 supertest, one Abbey location became bugged and tanks fall through it):

“The amount of testers on both the supertest and internal WG test is too small to check all the spaces, especially such retarded places where 90 percent of players almost never goes. That’s why in fact we have the common test. What pisses me off significantly more is the fact that even based on the results of the common test, measures are rarely taken due either to stupid bureaucracy or the limits of the engine, not allowing anything to be fixed quick.”

and

“The people have little time to test + they recruit anyone as a supertester these days and they don’t even listen to this weak testing (at least that’s my impression). Or they don’t explain why they left everything as it was, which causes additional butthurt of supertesters and messes up future quality testing, because it promotes the “why the fuck should we care, they don’t listen to us anyway” feeling amongst the supertesters.”

The bug, shown above was apparently discovered by supertesters, but WG did not listen for reasons listed above. The former developer further states that according to him, the supertest outlived its usefulness and would be more useful to be replaced by mass testing events.
