I have tried all the new USSR tanks. Overall they turn too slow, have very bad gun depression and they reload too slowly . 263 = good alpha but slow ROF, bad view/depression, slow turning.
257= good tank with slowish reload, bad aim time/depression.
ISM = Low pen/Alpha, bad view/depression, slow turning.
705 = bad depression, poor ROF/Alpha, poor view and slow turning.
705A = medium speed,poor turning, good alpha, poor ROF and depression.
430 = good speed/turning , bad depression with low alpha.
430U = Fast, mobile, good turning, good ROF but lowish alpha poor depression.
268v4 = fast but not nimble in turns,bad ROF but good alpha, bad depression.
The common fault is ROF, Depression, Mobility, and Alpha. All in all I will continue with the 257 and will wait to see whats after the t10. The rest I will not be grinding for in the near future. chuckwaggon Canada.
