You get wrong definition from the start.
4v4 is not 1v1 + 1v1 + 1v1 + 1v1.
Even there are 4 players, you have to cap 8 points. Not 2 points.
If you think you only cap 2 points, your enemy will take advantage and start ganging 2v1 or 3v1 upon you.
This is very important. I have seen many noob players camping peacefully while their teammate cry in pain.
4v4 in high level is often the same or even harder than 1v1, not only you have to coordinate with your friend, but sometimes you have to defend yourself against the impossible 1v2, 1v3.
+1, especially the part about 1 player camping, while the other 3 get pounded 4v3 on the other two points.
Fix several points for you.
ISU-152 spot commander is removed while Elefant 360angle spotting scope is kept.
JT destroys Churchill like knife through butter. With vet1 it can outrange and decrew atgun, 6 pounder included.
When I said unbalance, I meant greatly skewing the win rate. The JT and Elefant are still OP but there is a similar amount of cheese available to allies now to deal with them (also, they're really expensive so they should be a little OP). A year ago, players could just park a couple Elefants/JT's on two of the vp's and win in a 4v4.
The ISU is really bad for the cost now. The shell trajectory makes it hit almost nothing unless it is firing downhill and the AP shell doesn't reliably penetrate anything heavier than a Kubelwagen.
