I think everybody will agree that hand grenades act crazy. I think they need a serious improvement cuz now they are more toys than actual weapon. They often hurt or even kill the thrower himself.

Right now I can suggest 4 ways of improvement:

1) Increasing the speed of throwing power counter. There is no time to hold grenade in hands for that long when enemy reaches you. Almost in every situation it’s better to keep firing enemy with your primary weapon than to waste time switching to grenade, holding the key, throwing and waiting for explosion – it's about 5 sec – you can be easily killed twice during all this. That leads to my main suggestion:

2) At right click you throw grenade immediately with power about 80 (100 is too much I think)
Why do we need this? With that you can concentrate just on trajectory. You will be able to predict where it will jump, because power of throwing will be always the same.

3) Decrease rebound from surfaces. Sometimes they seem to gain more speed after hitting the wall. Just try to throw grenade in a narrow corridor – it’ll jump between walls as if it’s made of rubber. And again - it’ll help to build more realistic trajectories, that you can actually predict.

4) Aftermath situation - you remove safety pin and get killed. Logically grenade should fall near your body and explode. It would be more realistic and will bring new in-game situations.

I'm pretty sure that third one is just how the bouncing works, which is kind of ass.

I wouldn't mind a quickthrow option for the grenade. They could use a more reasonable bounce trajectory, low floor bounce but high wall bounce, being enough to bounce around a corridor corner but not much more.

Frag nades are great at the time being for weeding out far away campers. You can toss those things far, they have perfect fuse timers for long distance throws, they can skip over the ground well, and you don't have a lot of time to run from them after they've taken the time to travel to you.

The shrapnel is eh, though. Sort of thinking of removing it entirely and making the actual explosion radius a tad wider, as a concussion grenade instead (frag grenades are somewhat losing effectiveness in the modern day -- meanwhile no amount of body armour can block an organ-obliterating overpressure wave).

I miss that feature TBH, though I can imagine "Jihadnicians" would be quite a problem if it came back.

Fuck the bouncing, it's killed me so many goddamn times from somehow bouncing back at me from hitting a wall (because a+ physics).

If grenades was an inventory item you could throw them in battle. Using your third arm. Seriously though, what often gets me killed is the time it takes to switch from grenades back to your weapon

Personally I just have g bound to "use grenade" or whatevs.

Bam, instant grenade access. Then again I use number keys for all the weapons, scrolling's inefficient and clumsy

Probably just used to it

It's not about way of selecting grenades - for example I've solved weapon choosing problem via full rearranging weapon slots and binds.
It's about process of throwing - it's not user friendly at all. I don't understand why I can't throw them at full power instantly?
And what about 4) ? Isn't this is more fairly to people, who tried to use grenades and died to have a chance of dealing some damage?
