I personally think that engineering should both be nerfed AND buffed.
Hear me out, ok.
What if the available marine resources of engineering material, specifically metal, gets 2x’d or even 3x in Engi point buy (2 points instead of 5 for 10 metal), metal becomes something that comes a lot in free ASRS req crates, and is reduced in price by 2x when buyable (which is all easy to do since its only value changes) BUT, health for ALL variants of metal AND plasteel is reduced by 2x, and tailstab does 1.5x damage of slash to cades. Also buff construction pouch to give 4 spots instead of 3.
What does this do for those who do not understand how engineering works? Yes, SURE, this will give FOB more materials HOWEVER; there is a FINITE amount of space that engineers have to work with.
Skip what im about to type if you get why this is a nerf overall to FOB’s and a buff to the actual COMBAT technician part of your kit (aka building mini FOB’s at front to stop flanks / give medics a place to work):
Barricades have to be optimally built to accomadate WW1 firing line tactics of enough space to matter, but not too much so that you waste all your metal. Barricades have to be manned as well, so the more cade lines you make, the less human coverage you have. And even if you have the human coverage to cover all cadelines, now cades individually are weaker by 2x so they are very fast to melt down with focused hit and runs, especially with tailstab (an ability all but Vamp Lurker has) doing 1.5x of slash to a barricade.
This means that FOB’s will have more lines and are bigger, BUT, they are more vulnerable to focused hive flanks because the lines are weaker overall and will have less people holding each line since you have to cover multiple angles. Unless marines FOB camp the MOMENT they land, chinks in the FOB will be easier to focus.
Engineering explanation over.
TL;DR? This will force marines to keep the momentum with CT’s constantly using their now enormous amounts of roundstart metal to keep patching flanks and pushing as camping a 8 line FOB isn’t viable if you lose the front push.
Keep in mind this is spitballing but I am trying to account for the fact that if you make FOB weaker without compensating marines, you further enforce a helldive mentality; push into hive at all costs without stopping and lose or win in the first 10 mins, creating sub-50 min games with most of it being prep.
