Not sure about surrounding it with weaker tanks making the side armour issue irrelevant. It's not very hard for me to ignore the tanks you have on its side and just simply target your side armor of t-64BV. If you charge a bunch of weak tanks at me, one thing's for sure: I'll take advantage of the fact that you have crap side armour by merely positioning my troops at a 20 degree angle to your front armor (if they weren't positioned already to begin with) to get easy hits on side. And since the BV is probably going to be the biggest threat, I'd target my atgm's at it rather than your meatshields/the tanks on its side. And i usually keep atgms safe from meatshields charging them with my own tanks and infantry in fast carriers to unload right in front of charging T-55s or zhalos.
Putting weaker tanks next to your side armor does not at all make the side armor any more inaccessible to my rounds/ATGMs, nor does one need to actually be on the flank of the tank to hit its side armor. For that reason, I have personally phased out the T_64BV in my arsenal (in fact i've deleted the entire line off my deck).
Also, 130 points is alot to be traded for a few measly VTS1's or a friggin' Tow jeep missile...
Are you talking about 1v1 exclusely? Im not sure about that, it evolved a lot since i used BVs in 1vs1. But
you never charge in with BVs anyway and 16+ IFVs or Tanks can make up a huge screen, not to mention recon on the flank. You will have trouble getting into 2,4k ish range unnoticed. Its a fundamental flaw to allow tank hunters on the flank without reacting to it and of course BVs will be toast (as will most other tanks). Beside the T-64 are normal size so they are harder to spot aswell. Im not calling them the new fotm, i leave that to others.
Plus you get the 2nd best gun in Pact arsenal coupled with a good amount of missiles, etc.
Well yes i didn't mean to say charge. But even if you're stationary how do you know if i have say a Milan F2 squad inside a bush or forest 20 degree angle away from the direct front of your tank? Whether or not your tank is stationary, I can still hit its side, and you can't always 100% detect ATGM threats like infantry ATGMs (milan F2, 12AP, 1 hit KO half the time to the side of 64BV). In fact, to detect infantry on the edge of the forest, you'd have to fly / drive the recon right up to it until it is like 100m away. And I'll just turn off the ATGM until the big bad 64BV's come so that they don't shoot meatshield screens, only at BV. The normal size harder to spot argument you made is trivial as once you're within shooting range of me, you have already been spotted for the last 2000m by my 2e rep famas and gazelle. Normal =/= very small, especially if your tank is in the open (why would you put it in the forest anyway..). Normally when i face T80 + T64BV formations I always discover them at the same time simultaneously with recon.
However, to be honest, between the T80A and T=64BV it is a toss-up, as the BV is slightly more accurate with better front armor while the 80A's only advantage is side armor and speed. But the T80BV i would always use over 64BV because 80BV has 1. much better atgm 2. much better side armor (2 points is a HUGE difference) and 3. better speed. All this for a measly loss of 1 pt in accuracy of main gun I say hells yah ( I know the 80BV is also slightly more expensive but when you're buying high end tanks up in the 100s, 10 points is a trivial difference)
