I only played a couple hours of this game so far, but one thing I found to be disappointing during that time was that I was unable to vault over several different obstacles that I felt I should have been able to, as I would definitely be able to in real life, and I'm not even all that athletic.
The jump height and the height of objects that you are able to vault over are both a bit too low in my opinion. Please consider adjusting this so that we're able to jump a few inches or so higher, and vault over fences & walls up to at least head height of the player, if not a little more.
This would make navigating around the maps on foot feel a lot better in my opinion, and open up more strategic pathways to attack/defend instead of having boring predictable chokepoints that become meta for veteran players to camp and secure easy wins.
Implementing destruction physics on currently indestructible walls/buildings/etc, and things like tunnel digging, etc. would also help greatly in this regard, but I won't elaborate too much on other ways to help improve the tactical feel of this game so as to stay on topic as it relates to vaulting, which has already been implemented (just not up to my personal standards).
