Alright fellas lets get real here. The Engineer Techweb is underwhelming and needs a bit of a buff so it's not completely ignored like how it is usually. As an engineer main it hurts to go look at techwebs and see all T1 tech bought except for the engineer techweb. Without a doubt, it's not worth the 15 point investment because you get 1 sentry which once it's down, you're never gonna see it again. And that's it, one sentry. For the same 15 points you can get the medic upgrade which gives advanced burn/brute kits, super splints and a giga defibrillator. It would be very nice if it got a few things alongside the sentry. Here are some ideas:
Nanite Paste: Use on walls/cades/doors or structural things in general to give them more durability/passive health regen. When structure has acid on it, the acid negates the nanite health regen so it can be more easily destroyed.
Electron Beam Welder Tool: Essentially a better welder, don't need eye protection, welds faster and doesn't need fuel.
CMC (compact mobile cade) barriers: Similar to folding cades but are smaller, (can put them in like stacks of 5 in your welder pack, large item) have a faster deploy/pickup time and are a bit stronger. Helpful to secure a breach or secure a foothold at the front.
Sentinel Warning System (no relation to the xeno): A few warning systems that you can put on objects that when something without IFF walk by, sounds an audible alarm as well as sends the name of the warning system (SWS Delta 1 SWS Delta 2 whatever) as well as the coordinates, and map area that it's located in to the engineering/squad channel.
I don't think that you should get all of them, instead you get to choose 3. These are just some ideas to help incentivize getting the engineer upgrade. Feedback on this?
