barricades

Although it's not exactly the same, I have often placed the current barricade into the door or near a window and it feels more useful to me than having some planks there instead, as it provided a better cover and more or less unobstructed view. Plus, it's possible to deploy it even on places where a partially destroyed wall would prevent the "traditional" barricade. In other words, such system as it was in BFV feels a bit pointless for BF6 to me. :)

exactly, but it would be restricted to only being deployable to currently unaltered entry/windows?!

ok, well what about a subclass under engineer which would enable the option of reactive armor, however it would be a timed cooldown/single use per spawn?!

I liked the building feature in Battlefield V, but the current barricade deployable by support class works quite well for defending the positions, too.

Agree with comment on building mechanics 

The engineer has a supply depo gatget so that covers vehicles repairs, customization, as well as vehicles ammo resupply 

I'm not a big fan of the building mechanic like the one in Battlefield V. It was a very unpopular addition to the game, and I believe we'd be better off without it.

Emergency armor patch seems a bit unreal, so hard to believe something like this would be possible.

This is my opinion at least.
