Its isnt a problem, but its just even easier crouching. or so I find.

ive had no problem getting headshots while standing, heck even jumping

Crouching greatly effects the semi cone of fire, go try it out now, youl see what I mean.

SMG? Yes
Sniping with the rifle - not worth it. I dont even think crouching effects the semi....

^ YOUR doing it wrong, with the cone of fire, firing from a standing position is much harder, by having the fire ports on the 2nd block up you can shoot far more effectively, especially with the SMG.

your doing it wrong..
. Why don't people understand the make the firing holes the 3rd block up? That way you can crouch to dodge bullets. With your way, you can still get killed from a headshot/arms very easily. Trust me, its harder to hit those 3 pixels from someone head, then they're whole crouching body.

to build the one in the picture, around 20-30 blocks. Depending on how well you fortify it, thats why i say it works best on maps like pinpoint, its big tough and hard as a son of bitch to assault.

Building a big long one takes more time, but can be done fairly easily.

how long would the section of wall be? Because to create a front line for your team you need the stretch from one end of land to the other. (pinpoint, Island, etc)

^ 20 secs, max. Go try it out.

Personally, I like to rush up and create the new front line and quickly construct a cheap and fast wall, a 2 block high wall with a 3rd high between every other block. I usually don't have time to create walls like that.

^ haha, thanks, I spent a bit of time testing this design out, and In my opinion its far supior to any other type of "straight out of spawn, defence"

This wall is pretty good so now there is 3 building techniques i gotta use ingame o.O

Okay ill bump this ONCE.

Iv just added image 4, so you can see it in action! I took this 1 min ago on the pinpoint map :D

This is a indeed good,I always do this wall,but I don't use the holes,maybe I should try it some day.

Its strong, easy to build and defend, alot more grief proof then conventional walls, and doesn't use up ALL of your blocks. And the best part, takes no time at all to build and you can use it to safely attack at two different heights.

It also allows you to back up if your under heavy fire.

Firing from the ports are incredibly effective due to the additional blocks between the rifle and the exit hole, that way you cant be shot at diagonally by a sniper off to the side.

A wall designed perfectly for defending that can be built straight from spawn, no additional blocks needed.

* Especially effective in maps like pinpoint, when defending from a frontal assault is crucial*
