Gameplay: Block infantry through gate shields

[Hyncharas]

I do realise there is value in allowing Light Assaults to jump over walls and destroy gate shields but, after spending an hour running around a base to stabilise and kill any type of enemy that can breach, it gets really annoying for defenders after a while since they can't compete against cloakers and heavy assaults most of the time.

Gate diffusers should be kept, but I think only infantry should be able to get in the base if they're Light Assault, not any class that can just walk through the shield.
