We don't consider M6A2E1 as a direct counterpart of Lowe and KV-5 (however it doesn't mean it won't get any adjustments), T34 is going to fill this slot when added.
Yes, correct. However there won't be 6.7 update.
6.5 -> 6.6 -> 7.0
Thanks. If everything goes smooth 6.5 will go live before the end of June.
6.5 and 6.6 are relatively small updates. We are planning to release both by the end of July.
T30 will undergo the redivision later. Perhaps in 7.0.
