I'm not an armor player, so I can't say too much about the actual use of it, just when playing against it as infantry.
The IFV feels like it can shoot through all cover and deal damage no matter what's between it and you. If it shoots a concrete wall, the damage goes through the wall and hurts you, even though the wall is still standing. If it shoots the nose of an MBT and you're behind it, it still damages you somehow. When piloted by consoles, the thing will auto headshot you from 300m so long as they were aiming near you and pull the trigger.
Needs to take more damage from LAW and Jav, though should be more resistant to straight on attacks like from RPG and AT4, or the occasional Stinger or IGLA that hits it.
Like all armor, the secondary turret needs an auto leveler. So when your driver hits that pebble that launches one side of the tank 6 feet in the air, your scope doesn't just fly around in a headache inducing jarring fashion. It should at least try to stay on target unless it gets forced due to angle restrictions.
Also, the wonderful glitch to ADS speed needs fixed. I can't believe it was broken in the first place, then also that it hasn't been fixed in 2 significant patches.
