okay, the whole current grab system is messed up. solid line connection aswell as inability to break ALWAYS tend to deform players during doublegrab (shoulders missplacement, torso deformations and so on) and don't forget the increase ammount of force when grab applied, what makes it possible to dm, while grab should work more like a tool to absorb force.
part of this issue is solved with breakable grabs
another part is solved with grab implementations (ball socket axis connection instead of solid line, and some tweaking to make sure grab atleast doesnt cause increase of force applied, while ideal able to absorb force)
ofcourse, changing this mechanics will change actual meta, but it will add way more possibilities and depth to game.
with breakable grabs, shovel would not be so fatal aswell as torso grabs, since you will be able to break it, fucking up opponents torso by simple grab would not work that good, so the matches will be infact less glitchy and will allow more space to advance skillwise.
current grab system was created in 2006. it's no doubt outdated.
