Current grenade system is prone to breaking really often, so remaking the system to also make using grenades an actually viable option would be great.
I’m suggesting this because using grenades is only useful when, for example, being on top of CB, and MAYBE in a few ambushes but aside from that grenades aren’t really viable.
The way the rework could work is by adding much more range to the grenades by reducing the vertical height of the grenade’s throwing arc and increasing the horizontal distance they can travel. Surely if we’re strong enough to carry a juggernaut armor around we can chuck grenades really far away, too.
Also the main part of the rework could be to tie grenades to a key rather than making them equippable like everything else, so as to allow us to use them in many more situations without the risk of having to wait for our weapon’s equipping time.
