Now playing it in the game, my fears were confirmed. They gave it a slightly upgraded 122mm (D-2-5T to D-25T? Really?), but the armor is just as bad as before meaning 2 or 3 decent shots from a tier 5 kills the now tier 7 KV3. The people that have figured this out are now camping WAY back instead of using them as a heavy tanks purpose: a front lines tank.
Otherwise, KV1 is more like a slow Medium, KV2 is same as KV, both are slow bulky and mediocre, but make good roadblocks when they die.
Also i believe that the KV-5 needs to go up to tier 9, or at least more weight in MM towards higher tiers. With all the changes, KV5 is just too tough for its own tier (I am sure the prem buyers will disagree since they want to keep it tier 8 and too tough).
Are you SERIOUS?! In 7.2 live server, a fellow KV3 and I (i was a kv3 too), we were able to hold off three Tier 7's (T29, IS, TigerP), 2 Tier 6 (VK3601, Jpanzer4), and a Tier 5 (PZ 4) on Live Oaks in the Northwest portion of the map. Saying its "BARELY" able to hold its own against contemporary tanks is a serious understatement...
P.S. we both died in that battle but were able to hold them off long enough for our team to cap.
