What is the point of bricks?

[La Ley Innata]

I can only think that their use is as a cheap high damage weapon that can break (but pay you back more or less what it costed depending on the wave), and the engineering scaling only makes sense with the builder, all other classes are way better with tools, idk that weapon confuses me

Blue bricks are great economy wise, you pay maybe 7+7, combine into a blue brick that breaks into 30 material. That is also 30 experience (or more depending on your XP gain). Combining above blue lose out on materials compared to the blue brick though, weirdly enough. If I get a brick in the first shop I try to get two to hopefully break it fast, but either way it usually breaks in a few waves.

I guess you can minmax your economy like that, I think it just bothers me that the materials they drop can be lower than the materials you used to buy them, I wish they scaled with the wave, even if you end up with a lot more materials than the ones you used to buy them.
Even if they give 3 times as many materials at wave 20, that would only mean +20 materials compared to the initial 10, a 23 materials profit thanks to the luckiest tier 1 brick seems weak to me tbh, but that wouldn't bother me as much as they currently do

Definitely a flawed item, should only be available in the first few stores, so they don't take a place for something useful.

They have incredible base stats even a level 0 brick has better stats than most if not OF all weapons.
They are bad late game as they can break even in boss wave (yes has happened to me, how could it not?)
I find them funny enough to smash everything with them and then transition to something else

They hit very hard.

I picked one after wave 1 and it broke on the very first hit. Fun times.
I feel like it's just a temporary item to boost your aoe clearing ability early on, but overall it's a poor item beyond that.

Everyone's comments seem to just reinforce the fact that it should not be available in the store past the early waves.
