Ok, some general stuff about throwing grenades:

- Always make sure you won't hit your team mates. There have been so many times when I've thrown a grenade and it's either exploded near a team mate, either killing, damaging, or blinding them -- or, worst case scenario, you throw one in a group of team mates, it bounces off them, and your whole team goes down 'cause of you (it's a priceless moment, but not a good one).

- Get familiar with where your grenades will land. Practice alone on a map and try bouncing them off walls and such, figure out how they react at distances and such. All too many times I've bounced a grenade off the wall to have it land within distance of me (and sometimes blow me away).

- If you're behind your team mates, don't throw a grenade. If you are, tell them you think it would be wise to throw a grenade somewhere, specify where, and have someone in the front do it. I break this rule of my own a lot, but I think I'm finally fixing that.

Edit:
- When blinded, I usually retrace my steps back to somewhere I think is safe (usually not an option). If I can't do that and I know ahead of time, I'll try to find something to protect myself from the flash so it doesn't last too long (maybe a second at most), and then I can usually recover fast enough to defend myself (and die in the process XD). If I'm completely blinded, I don't spray and pray because I might end up hitting a team mate. So, I usually crouch, and pray to god that I don't die.

Edit 2:
- If you see asch with a grenade, run and pray.

Mostly common sense stuff (I think), but I felt like sharing it.

If anyone thinks something is wrong with that, lemme know.
