Quick tool menu allow palyers to quickly change tools or weapons to suit their immediate situation. By exemple using a long range rifle and switching to melee weapon to handle a sudden close range encounter.
When alone or in a non combat situation I'm able to switch my tool from 1 to 4 instantaneously (less than half a second) however when I'm engaging a combat scenario it always seems to have a delay 3-4 seconds before starting the animation. This create a scenario where I'm unable to quickly access proper tools to defend myself which leaves me vulnerable.
