Why are grenades so cheap?

I guess cheap is the wrong word, because that would mean that they're not only inexpensive but made poorly as well and would be mostly ineffective. I just cant understand why grenades cost less than most objects. You can also buy eight of each at a time.

Can we not have grenades be dirt cheap next wipe and just try it out?

or alternatively can someone explain to me why they're dirt cheap? is it to counter the cheaters who farm labs so that they cant make extra money off of the hundreds of raider grenades?

It would be nice to understand why nade spam is not only allowed but encouraged. It's not like its horrible for the game, I just think its kind of annoying and adds onto the bs "meta" this game has unfortunately developed. I hate metas.

It just seems like players don't have to think tactically about fights. Why would you when you could just mindlessly nade spam until you get an advantage from it. I feel like you should be allowed to play that way but it should cost you more than 70k roubles to throw 10 grenades at someone. Then you kill the enemy you're fighting and take their 10 nades they bought for dirt cheap.

At least make the player think about how they're going to utilize a grenade, you know? Don't you guys think grenades are a little (or a lot) underpriced. I really think they are significantly more valuable than the price makes it seem.
