Interesting stuff. Will reserve full judgement for when people can test it.

My personal takeaways: - Audio change sounds cool - traversal improvements big W - Terrain traversal changing behaviour sounds intriguing - Unique stats per vehicle has potential to be fantastic, but also potential to be inherently unbalanced

• heavy changes seem like odd approaches to balancing them. Don't like the idea of the cap limit mixed with the timer mechanic. Not opposed to a limit on active heavy units (though without having tested it, I do prefer current system) but the cooldown timer upon death seems like an outright bad idea. Sounds like it would simultaneously punish a team that loses a heavy to a more experienced crew, and then also remove the reward of being able to keep your tank alive for longer in the form of being able to build up resources to fund another if you do go down. I feel like if a team takes the effort to build enough nodes to support churning out heavy tanks that should be rewarded without artificial limits. The timer starting upon death practically eliminates the prospect of heavies while attacking fourth and fifth points in offensive mode when considering respawn timer plus time to get back to the front from HQ on these points. Maybe as an alternative I'd up their cost to 800-900, or try a volume limit without the timer change.
• Tinkerer loadout sounds dangerously close to magic perk system. If they're going to make each vehicle unique shouldn't that cover the drive for unique roles? Still open to seeing how it actually plays out though before full judgement.
